Question

Jayne stopped to get gas before going on a road trip. The tank already had 4 gallons of gas in it. Which equation relates the total amount of gasoline in the tank, y, to the number of gallons that she put in the tank, x?

y=4+x
y = x − 4
y = 4 · x
y = x ÷ 4

Answer 1

y = 4 + x

Reason: the tank already has 4 gallons, and she adds x gallons, so total y is 4 plus x.
