Question 885424
I'm assuming you meant to say "24 mpg on the highway"



(24 mpg)*(x gallons) = 205 miles


24x = 205


x = 205/24


x = 8.54166666666667



Round up to get 9 gallons. You need 9 gallons to drive 205 miles. 


Note: Don't round down to 8 because 8 gallons is not enough (notice how 24*8 = 192 miles)
