Answer:

3.2 gal

Step-by-step explanation:

given:

825 sq ft require 1 gal,

hence the unit rate for the paint coverage is,

= 1 gal / 825 sq ft

= (1/825) gal per square foot

given that we need to cover 2640 sq. ft, this will require

2640 sq.ft x unit rate for paint coverage

= 2640 sq.ft x (1/825) gal per square foot

= 3.2 gal
