Given: Samantha drove a total of 700 miles on her vacation. If her car averages 35 miles per gallon of gas and gas cost an average of $1.25 per gallon.

Asked: How much did she spend on gas during her vacation?

Samantha drove a total of 700 miles on her vacation. If her car averages 35 miles per gallon of gas and gas cost an average of $1.25 per gallon.

Total gas consumed = 700 miles / 35 miles /gallons = 20 gallons

Cost of gas = 20 gallons * 1.24 $/gallons = $25

IMO B

Total Cost = Fuel used * cost per unit Fuel.
Miles per gallon = 35
Total miles accumulated = 700
So total fuel used = 700/35= 20 gallons
Cost per gallon = $1.25
So total cost = 20*1.25= $25

700/35 is 20.
20*1.25 is 12.5*2 which is 25
IMO B

Samantha used 700/35 = 20 gallons of gas, so she spent 20 x 1.25 = 25 dollars on gas.

Answer: B
