Answer:
$80.59
Step-by-step explanation:
You add the price of the raincoat and shoes to get 152.75, you then subtract the price of the 4 shirts you returned to get 76.75. The 5% tax for this is 3.84 so you add the two together and you get $80.59.
Hi!
The set up for the question is like this:
![\frac{4x + 5}{6} = \frac{7}{2} \\2*(4x + 5) = 7*6\\8x + 10 = 42\\8x = 42 - 10 = 32\\x = 32/8\\x = 4](https://tex.z-dn.net/?f=%5Cfrac%7B4x%20%2B%205%7D%7B6%7D%20%3D%20%5Cfrac%7B7%7D%7B2%7D%20%5C%5C2%2A%284x%20%2B%205%29%20%3D%207%2A6%5C%5C8x%20%2B%2010%20%3D%2042%5C%5C8x%20%3D%2042%20-%2010%20%3D%2032%5C%5Cx%20%3D%2032%2F8%5C%5Cx%20%3D%204)

Step-by-step explanation:

If the length of side of base is 14 inches and height is 6 inches of pyramid a then the volume of pyramid a is 12.5% of pyramid b and volume of pyramid a is 8 times bigger than volume of pyramid b.
Given the length of side of base of pyramid a is 14 inches , height of pyramid a is 6 inches and volume of pyramid b is 3136 cubic inches.
We have to determine the percentage and number of times that volume of b is bigger than volume of pyramid b.
Volume of a square pyramid=base area * height/3
Base area = Side * side
=14*14
=196 inches square.
Volume of pyramid a =196*6/3
=392 cubic inches.
Percentage=Volume of pyramid a / volume of pyramid b*100
=392/3136*100
=12.5%
Let the number of times be x.
So,
392*x=3136
x=3136/392
=8 times.
Hence the volume of pyramid b is 8 times bigger than volume of pyramid a and the percentage is 12.5%.
