I believe this is $24.25
Total paid = $296
Number of tickets = 16
Cost per tickets = 296/16 = $18.5
This cost excludes the $5.75 saved due to the group.
Original price = $18.5 + $5.75 = $24.25

Answer:
a. 3.1 acres
b. 7.44 acres
Step-by-step explanation:
a.
0.25 can also be written as 25%
to find 25% of 12.4 do:
25/100 * 12.4 (cross multiply by 4)
= 25/25 * 3.1
= 1 *3.1
= 3.1

Simplify the exponents. Please show me how to do the step by step?? I'm not sure how to solve these when they have parentheses
Answers
(2n²•n³•3n¹)²
First, simplify inside the parentheses. We multiply the coefficients and exponents. The coefficients: 2×3=6. and the exponents: 2×3×1=6. All together that gives: [tex](6n^6)^2[/tex]Then multiply the inside of the parentheses by itself since it's the exponent is 2. Therefore we end with [tex]36n^12[/tex]
(y•4y²)³
Same approach. Multiply the inside which gives [tex]4y^3[/tex] Then calculate that to the power of 3.
[tex]4y^3[/tex]×[tex]4y^3[/tex]×[tex]4y^3[/tex]=[tex]64y^9\\[/tex]

Julia has $80. She wants to purchase a nail paint set for $16 and earrings. She spends the rest of the money on earrings. Each pair of earrings costs $8. Write an inequality for the number of pairs of earrings she can purchase.
Answers
after the nail set is bought, she will have 80-16 left, that is 64. If each pair of earrings costs 8 dollars, then she can buy 64/8 =8: She can buy 8 pairs of earrings.
If the question is interpreted that she doesn't spend all her money, then we could say, if we must that if y=number of earrings she can buy then
Your answer is y≤8

now, we know that 18.9% of "x" is 43100, what the dickens is "x"?
[tex]\begin{array}{ccll} amount&\%\\ \cline{1-2} x & 100\\ 43100& 18.9 \end{array} \implies \cfrac{x}{43100}~~=~~\cfrac{100}{18.9} \\\\\\ 18.9x=4310000\implies x=\cfrac{4310000}{18.9}\implies x\approx 228042[/tex]

solve the equation for y: y + 7 = 5/4 (x + 16)
Answers
To solve the equation for y, we need to get y by itself on one side of the equation.
The first step is to get rid of the fraction on the right side of the equation by multiplying both sides by 4:
4y + 28 = x + 16
Then, we need to move the x term to the left side of the equation by subtracting x from both sides:
4y + 28 - x = 16
Then, we need to move the constant term 28 to the left side of the equation by subtracting 28 from both sides:
4y - x = -12
Finally, we have the equation in the form y = (1/4)x - 3, so the solution for y is y = (1/4)x - 3
It is important to note that in this solution we have used the distributive property and followed the order of operations to get to the final result, if you don't follow this steps you might get a different result.
STEPS FOR SOLVING LINEAR EQUATIONy+7=45(x+16)Use the distributive property to multiply 45 by x+16.y+7=45x+20Swap sides so that all variable terms are on the left hand side.45x+20=y+7Subtract 20 from both sides.45x=y+7−20Subtract 20 from 7 to get −13.45x=y−13Divide both sides of the equation by 45, which is the same as multiplying both sides by the reciprocal of the fraction.4545x=45y−13Dividing by 45 undoes the multiplication by 45.x=45y−13Divide y−13 by 45 by multiplying y−13 by the reciprocal of 45.x=54y−52SOLVE FOR Yy=45x+13
