Question

you have approximately 1/4 of tank of gas.your tank holds 20 gallons.how much gas do you have left? if you plan to fill the tank,how many gallons will you purchase? if gas cost $21/2 per gallon,how much will it cost you to fill up

Answer 1

Explanation:

if you have a quarter tank then what is empty is 15 gallons because 20*3/4=15

you now need to fill up the 15 gallons, if each gallon is 21/2 dollars then 15*21/2 should give us a price. 21/2=10.5

15 gallons*10.5 dollars=$157.5 for the final price
