Answer:
A
Explanation:
Given,
The quote from Company A is $0.15 less per square foot than the quote from Company B,
That is,
Quote from Company B for 1 square foot - quote from Company A for 1 square foot = $ 0.15
Quote from Company B for 1200 square feet - quote from Company A for 12 square feet = 1200 × 0.15 = $ 180,
Hence, for buying 1,200 square feet of carpet company A is cheaper by $180 than company B.
