Xavier is driving home. He starts 250 miles from home and his car can travel 28 miles per gallon of gasoline he uses. Xavier stops at a rest stop that is 100 miles from home. Let g be the amount or gas he has used at that point. Set up and solve an equation for how much gas Xavier used to get to the rest stop.

For 100 miles he uses 3.571 gallons of gasoline.

In equation form it is y/x*100

Step-by-step explanation:

Unitary Method

He travels 28 miles per gallon of gasoline.

For 1 mile he uses  1/28 gallons

For 100 miles he uses 1/28 * 100= 100/28= 3.571 gallons of gasoline.

Let x be the miles and y be the gallons of gasoline used to travel x miles.

Then for 1 mile  the gallons of gasoline used will be y/ x gallons.

For 100 miles  the gallons of gasoline used will be y/x *100 gallons.

In equation form it is y/x*100 gallons for 100 miles where x is the number of miles and y is the amount of gallons.
