Tara is painting her house. There are a total of 2,238 square feet of surface area to be painted. If she can paint 64 square feet of surface area per hour, which equation would represent A, the surface area of the wall left to paint, after she Tara has painted for t hours?

A = 2,238 - 64t
A = 64 - 2,238t
A = 2,238 + 64t
A = 64 + 2,238t

    A = 2,238 - 64t
    A = 64 - 2,238t
    A = 2,238 + 64t
    A = 64 + 2,238t
