Roy drives a sedan that gets mileage of 30 miles per gallon. If fuel consumption is represented by g and mileage by m, which function represents the relationship between m and g?
m = f(g) = 30 × g
m = f(m) = 30 × m
g = f(m) = 30 + m
m = f(g) = g − 30
m = f(g) = g ÷ 30

Respuesta :

m=f(g)=30 x g 

Think about it - if the car has 5 gallons of gas then
m=f(5)=30 x 5
m=150
