Question

The Rodriquez family drove 115 miles on 5 gallons of gasoline. Which of the following equations can be used to find how far they can travel on a full tank of 18 gallons?

Answer 1

115 miles on 5 gallons....115/5 = 23 miles per gallon

so ur equation is : y = 23x....where x is the number of gallons and y is the total miles

for 18 gallons....sub in 18 for x
y = 23x
y = 23(18)
y = 414 miles <=
