The ordered pair relating number of gallons of gas, x, to the total cost of the gas, y is (3.2, 12).
An ordered pair refers to the coordinates of a point such that “x” is the x-coordinate and “y” is the y-coordinate.
The total budget that Berto has for gas in his car = $12
The unit cost of gas per gallon = $3.75
Let the total cost of gas = y
Let the number of gallons of gas = x
The maximum quantity of gas that Berto can afford = Total budget for gas/ cost per gallon
= 12 / 3.75 = 3.2 gallons
Thus, the coordinate or ordered pair for gallons of gas and Berto's budget (x, y) = (3.2, 12).
