4(5x + 7) = 128
First, I'd do distributive property and get:
20x + 28 = 128
Then, subtract 28 from each side.
20x = 100
Next, I'd divide 100 by 20 = 5
x = 5
4 *(5(5) + 7) = 128
5 * 5 = 25
4 * (25 + 7)
4 * 32 = 128
Therefore, the perimeter = 2l + 2w
l = 4
w = 5x + 7
BUT we know that x = 5
w = 5(5) + 7 = 32
2(4) + 2(32)
8 + 64 = 72
Therefore, the perimeter would be 72 inches.

<h3>Part A</h3>
As per the given information there are 4 different price intervals.
<u>Let x be the age and y be the admission price, then we have following equations;</u>
- y = 10.50, if 15 ≤ x ≤ 61
- y = 8.50, if x ≥ 62
- y = 6.50, if 2 ≤ x ≤ 14
- y = 0, if 0 ≤ x ≤ 1
