Question

Berto has $12 to put gas in his car. If gas costs $3.75 per gallon, which ordered pair relating number of gallons of

gas, x, to the total cost of the gas, y, includes the greatest amount of gas Berto can buy?

Answer 1

(3.2, 12)

Explanation:

Total cost for gas = $12

Cost per gallon = $3.75

Letting total cost of gas be y and number of gallons be x, maximum number of gallons of gas he can buy would be ;

Total cost of gas/ cost per gallon = 12 / 3.75 = 3.2 gallons

Therefore , the coordinate pair (x, y) = (3.2, 12)

Answer 2

(12, 3.2) would be the max amount of gas he could buy. (11.25, 3) for an even gallon amount.
