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 gas, y, included the greatest amount of gas berto can buy?

(3.2, 12)

Step-by-step 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)
