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 =(12)/(3.75)\ gallon\\\\Units = 3.2\ gallons](https://img.qammunity.org/2021/formulas/mathematics/high-school/tmimenx14duliltast9kou1yvg61f569b2.png)
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 .
