Answer:
2.95
Step-by-step explanation:
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.
