Answer 1

Given :

Total money Beto have , P = $12 .

Cost per gallon , c = $3.75 .

To Find :

Ordered pair of lading number of gas to the total cost of gas includes the greatest amount of gas she can buy .

Solution :

Now , number of gallons she can buy for $12 is :

$Units =\dfrac{12}{3.75}\ gallon\\\\Units = 3.2\ gallons$

So , the greatest amount of gas she can buy with $10 is 3.2 gallons .

Therefore , the ordered pair is ( 3.2 , 12 ) .

Hence , this is the required solution .
