Amy can paint a room in 12 hours. alicia can paint the same room in 16 hours. how long does it take for both amy and alicia to paint the room if they are working together? write an equation that using the variable t to represent the time it takes to paint the room together that can be used to solve the problem.

Well 12 is 3\4 of 16 so honestly it would take the 8 hours working together.

As far as formula if I had to guess it would look like.. 12Amy(Ay)- 16Alicia(Aa) = 4 hours minus 4 from Amy would be 8hours.

in fraction form might make more sense. 3\4 - 4\4 = 1/4 minus that from Amy and she'll finish together with Alicia 4 hours quicker being 8hours.
