The Pythagorean Theorem is used to find the unknown length of a side of a triangle or (in your case) a pyramid. The Pythagorean theorem is a^2 + b^2 = c^2 with c being the hypotenuse (longest side). Use this theorem to find each of the lengths of the sides of the pyramids that you need to find the volume of each respective pyramid.

Answer:
Total cost of CD player = $58.52
Step-by-step explanation:
Given data:
Price of CD player on sale= $54.95
Local sales tax = 6.5%
Total cost of CD player = ?
Solution:
Local sales tax= (6.5 * 54.95)/100 = $3.57
Total cost of CD player = Price of CD player on sale + Local sales tax
= $54.95 + $3.57
Total cost of CD player = $58.52
Old price=new price/(1+inflated rate)
=2000/(1+1.08)
=185.19 (approximately)
