2.1.PS-17Question HelpSome people advise that in very cold weather, you should keep the gas tank in your car more thanhalf full. Lou's car had 5.2 gallons in the 13-gallon tank on the coldest day of the year. Lou filled thetank with gas that cost $3.80 per gallon. How much did Lou spend on gas?

Answer 1

the tank is 13 gallons so halve of it is:

`(13)/(2)=6.5`

And the total gallons he will need is:

`13-5.2=7.8`

and the unit rate is 3.80 so the cost will be:

`7.8\cdot3.80=29.64`
