Problema Solution
Two girls went on vacation and they agreed to split all the expenses. The trip was prepaid so Mary wrote a check for food ($56.98) and one for lodging ($83.29). Clare wrote the checks for gas ($41.96) and entertainment ($37.47). How much does Clare owe Mary.
Answer provided by our tutors
Mary paid total of:
56.98 + 83.29 = $140.27
Clare paid total of:
41.96 + 37.47 = $79.43
Since they agreed to split the expenses, they should split the difference:
(140.27 - 79.43)/2 = $30.42
That is, Clare owes Marry $30.42.
