Question

You work for a carpet company. You sell carpets: 100 square feet for $67,200 square feet for $130,400 square feet for $240, and 800 square feet for $504. What is the approximate percentage difference for the two best carpet deals according to their unit costs?

A. 3%

B. 4%

C. 5%

D. 7%

Answer 1

Answer: 5%

Explanation:

Calculate unit cost

$67/100 = $0.67/sqft

$130/200=$0.65/sqft

$240/400=$0.60/sqft

$504/800=$0.63/sqft

Then compute

(Difference between two best deals)/(Average price of two best deals)

(.03)/0.615 = 5%

Answer is C (5%)

Answer 2

I don’t know exactly but I tried the math and it’s either 4 or 5%
