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

Answer:

$(3.2, 12)$

Explanation:

Step1: Calculate number of gallons

We use the formula $x=\frac{y}{cost - per - gallon}$. Given $y = 12$ and cost per gallon is $3.75$, so $x=\frac{12}{3.75}=3.2$.

Step2: Determine ordered - pair

The ordered pair is $(x,y)$. Since $x = 3.2$ (gallons) and $y = 12$ (total cost in dollars), the ordered pair is $(3.2,12)$.
