Question

A painter paints rooms in a house. The painter purchases 12 gallons of paint and uses 4 gallons on the first day of work.

Which equation could be used to find how many gallons of paint are left, g?


g+4=12


g÷12=4


4×g=12


12+g=4

Answer 1

g+4=12

Explanation:

Since the painter used 4 of the 12 gallons, the painter now has 8 gallons, so g=8.

The equation g+4=12 represents this because if we solve it by isolating g then we get that g=8.
