Question

Some people advise that in very cold​ weather, you should keep the gas tank in your car more than half full. LouLou​'s car had 6.56.5 gallons in the 1616​-gallon tank on the coldest day of the year. LouLou filled the tank with gas that cost ​$3.703.70 per gallon. How much did LouLou spend on​ gas?

Answer 1

Answer:
`\$35.15`

Explanation:

Based on the data given in the exercise, we know that the car has 16​-gallon tank and on the coldest day of the year Lou​'s car had 6.5 gallons.

Then, the amount of gallons of gas Lou bought to filled the tank is:

`16\ gallons-6.5\ gallons=9.5\ gallons`

Knowing that the cost per gallon of that gas is $3.70, you can calculate the total amount of money Lou spent on gas by multiplying the cost per gallon by the amount of gallons of gas Lou bought to filled the tank.

Then:

`Total\ spent=(9.5)(\$3.70)\\\\Total\ spent=\$35.15`
