Question 148607: Over the weekend, Rachel and morgan drove to chicago to go shopping. Now they are preparing to go home. Morgan needs gas for her jeep, which get 26 miles per gallon for gas mileage, when she stops at the gas station, she already has 10 gallons of gas in her tank. She buys $1.60 per gallon.
If Morgan spends $21.00 on gas, what is the total distance the girls could travel? Round to the necessary, to the nearest tenth

You can put this solution on YOUR website!
x=gallons of gas
y=miles
160x=2100 *(160 and 2100 is the money in cents)
26(x+10)=y

160x=2100
x=13.125
26(13.125+10)=y
26(23.125)=y
601.25=y

distance=601.3 miles
