A coffee shop sells a coffee refill mug for $6.75. Each refill costs $1.25. Last month Kim spent $31.75 on a mug and refills. Write an equation you can use to find the number of refills Kim bought. How many refills did Kim buy?

Answers

Answer:

equation: x(1.25) + 6.75 = 31.75 refills: 20

Step-by-step explanation:

The mug costs $6.75, and you aren't buying multiple cups, so that number stays the same. The number of refills is "x" since we do not know the amount. Next to "x" we multiply 1.25 for the cost of each refill. So now we have "x(1.25)" then we add $6.75 to the equation, for the mug price. Along with the total at the end. To which we now have "x(1.25) + 6.75 = 31.75"

Now we solve the equation. First, subtract 6.75 from each side

x(1.25) + 6.25 = 31.75

            -6.25    -6.25

Now we have "x(1.25) = 25" So we have to divide each side by 1.25

x(1.25/1.25) = 25/1.25

                x = 20

Therefore, Kim bought 20 refills. To check our work we can replace x with 20 in the original equation.

20(1.25) + 6.75 = 31.75

        25 + 6.75 = 31.75

                31.75 = 31.75

Answer:

7 lbs. or option B.

Step-by-step explanation:

To figure out how much the chairs weigh to then divide them, you first need to subtract 36 from 92.

92 - 36 = 56

Now, we have to divide 56 by the number of chairs we have because we need to find out how much a single chair weighs.

56 ÷ 8 = 7

So, each chair weighs 7 lbs.

Answer:

B) 7 lbs

Step-by-step explanation:

To find how much the chairs weigh, you must subtract 36 from 92.

92 - 36 = 56

We have to divide 56 by 8 or the number of chairs.

56 ÷ 8 = 7

B) 7 lbs

Answer:

This represents the graph area above the line y = 4x - 5 shaded.

Step-by-step explanation:

y > 4x - 5 is an inequality.  First we graph y = 4x - 5, which has y-intercept (0, -5) and slope 4.  Next, we shade all of the area above this line (because the inequality y > 4x - 5 says that all y values are above 4x - 5).
