Suppose you have $1500 and want to have $8000 in 15 years. What simple interest rate will you need? Please tell me
Answers
Answer: Rate = 0.289 or 28.9%
Step-by-step explanation:
To determine the simple interest rate required to turn $1500 into $8000 in 15 years, we can use the formula:
Simple Interest = Principal x Rate x Time
where:
Principal = $1500
Time = 15 years
Simple Interest = $8000 - $1500 = $6500
Substituting the given values, we have:
$6500 = $1500 x Rate x 15
Simplifying the equation:
Rate = $6500 / ($1500 x 15)
Rate = 0.289 or 28.9%
Therefore, a simple interest rate of 28.9% is required to turn $1500 into $8000 in 15 years. Note that this assumes that the interest is compounded annually. If the interest is compounded more frequently, a lower interest rate would be required to reach the same goal.
The values in the table describe a data set.

Median 35
Interquartile Range 10
Maximum 55
Which value can be used to describe how the values in the data set vary with a single number?
A. median
B. maximum
C. interquartile range
D. mean
Answers
The IQR is 10, indicating the middle 50% of the data values lie within the range of 28 to 43 (35 +/- 10 is 28-43).
The other choices are:
Mean (30) - Describes the central tendency but not variability.
Median (35) - Also describes central tendency but IQR gives a better sense of spread.
Maximum (55) - Only describes the upper limit, not variability.
So the interquartile range (IQR) of 10 is the best choice to capture how spread out or varied the values in the data set are.
The answer is C. interquartile range

D. Mean Absolute Deviation

Julia wants to put $56,000 into a savings account for 8 years and increase her total to at least $100,000. Assuming the interest is not compounded, what rate of return does the account need to earn?
Answers
Answer:
the account needs to earn a rate of return of at least 9.82% per year to increase Julia's total to $100,000 in 8 years with simple interest.
Step-by-step explanation:
To find the rate of return that the account needs to earn, we can use the simple interest formula:
Simple Interest = Principal x Rate x Time
Where:
- Principal = $56,000
- Time = 8 years
- Simple Interest = $100,000 - $56,000 = $44,000
Plugging in the values, we get:
$44,000 = $56,000 x Rate x 8
Simplifying the equation, we get:
Rate = $44,000 / ($56,000 x 8) = 0.0982 or 9.82%
Therefore, the account needs to earn a rate of return of at least 9.82% per year to increase Julia's total to $100,000 in 8 years with simple interest.
Answer: 9.82%
Step-by-step explanation:
So first of all we need to put down our formulae. We know that:
Simple interest = Principal × Time× Rate / 100
However the question is looking for Rate , therefore we must re -arrange the equation and make Rate the subject . This will give us :
Rate= Interest × 100 / Time × Principal
Now , the question tells us that the Principal is $56,00 and the time is 8 years , but we do not know the interest. In the case , we will use the equation :
interest =Amount -Principal to find the interest ,since the total amount has been given to us.
100,000 - 56,000 = 44,000
Principal =56,000
Time = 8
Interest=44,000
Using the first formulae:
44,000×100 / 8×56,000 = 9.8
Rate is always in % so our answer is 9.82%

of your work.
ANSWER BOTH QUESTIONS QUESTION A AND QUESTION B.
Answers
Answer: A) $333
B) $468
Step-by-step explanation:
A) First we multiply. 130x5=650 Now we know that we have to get $650 total in 5 weeks in order to get an average of $130 per week.
87+105+125=317
650-317=333
Necolai has to earn $333 the fifth week to achieve an average of $130 per week.
B) 28% of 650 = 182
Now subtract the taxes from his earnings. 650-182=468
Necolai has $468 of his total pay after taxes.
To find how much Necolai has to earn in the fifth week to achieve an average of $130 per week, we have to use the concept of mean.
The average of five weeks' earnings should be $130. Therefore, the sum of his five-week earnings should be:
5 * 130 = 650
Necolai's total earnings for the first four weeks are:
87 + 105 + 125 + x (earning in the fifth week) = 317 + x
317 + x + y = 650
where y represents his earnings in the fifth week. Solving for y, we get:
y = 650 - 317 - x
y = 333 - x
So, Necolai has to earn $333 in the fifth week to achieve an average of $130 per week.
Question B:
After earning $87, $105, $125, and x dollars (from the third week), Necolai’s total earning are $317 + x. After 5 weeks, Necolai has to pay 28% in taxes, which means he gets to keep 72% of his earnings.
The taxes are calculated as:
Taxes = 0.28 * (317 + x)
Taxes = 88.76 + 0.28x
Therefore, the taxes he has to pay after five weeks are $88.76 + 0.28x.
The portion of his total earnings that he keeps after taxes is:
Total earnings - Taxes = (317 + x) - (88.76 + 0.28x)
Total earnings - Taxes = 228.24 + 0.72x
Therefore, after paying taxes, Necolai is left with $228.24 + 0.72x of his total earnings.
A jacket has an original price of $50. You have a 20% off coupon. The sales tax will be 4%. What will you pay for the jacket after the discount and sales tax?
Answers
20% * $50 = $10
So the discounted price of the jacket is:
$50 - $10 = $40
Next, we need to calculate the sales tax on the discounted price. The sales tax is 4% of the discounted price of $40, which is:
4% * $40 = $1.60
Finally, we add the sales tax to the discounted price to get the total price:
$40 + $1.60 = $41.60
Therefore, you will pay $41.60 for the jacket after the discount and sales tax.
Answer:
$41.6
Step-by-step explanation:
The formula to find discount is (discount% x Original price) - original price.
In this case, that would be .20 times 50, which is 10.
Now you need to subtract 10 from 50, which is 40.
40 is the discounted price of the jacket before tax.
To find the tax price, you need to multiply the store price times the % tax, and add it to total cost.
In this case it would be 40 x .04, which is 1.6.
Now you add 1.6 to 40 which is $41.6.
Therefore, you will pay $41.6 for the jacket.

Answers
Answer:
The equation: 2+x=-12 goes to D
The equation -12+x=2 goes to C
Step-by-step explanation:
2+x=-12 goes to D because they said that the temperature fell to -12 degrees, meaning the end temperature was -12, so -12 has to be isolated on one side of the equal sign.
-12+x=2 goes to C because they said that the temperature rose to 2 degrees, meaning the end temperature was 2, so 2 has to be isolated on one side of the equal sign, making this the correct format.
