Question

A cleaning product sells for $0.75 a quart. Which equation can be used to solve for the total cost, C , of five gallons of the product? A: C = $0.75 × 4 + 5 B: C = 5 × ($0.75 × 4) C: C = ($0.75 + 4) × 5 D: C = ($0.75 × 5) + 4

Answer 1

Answer: b. C = 5 × ($0.75 × 4)

Explanation:

Note that 4 quarts = 1 gallon

Therefore, if a cleaning product sells for $0.75 a quart, the equation can be used to solve for the total cost, C , of five gallons of the product will be:

= 5 × ($0.75 × 4)

= 5 × $3

= $15
