All you have to do is change the cups to gallons And then how ever many gallons it cost u mutiple that buy the cost per gallon (3.12) hope this helps
We already know that 1 cup= 0.0625 gallon.

100 cups of gas* (0.0625 gallon of gas/ 1 cup of gas)= 6.25 gallons of gas.

6.25 gallons of gas* ($3.12/ 1 gallon of gas)= $19.50.

The gas cost $19.50~
