C should pay E $\$2$. B should pay A $\$14$ B should pay D $\$4$

Work Step by Step

A spent $\$42$. B spent $\$10$. C spent $\$26$. D spent $\$32$. E spent $\$30$. The total amount spent is: $42+10+26+32+30=140$ The amount spent per person is: $140\div5=28$ dollars. This is the amount they all should have spent. To find out how they can resolve the discrepancies, we need to calculate how much each individual owes or is owed. A is owed $42-28=14$ dollars. B owes $28-10=18$ dollars. C owes $28-26=2$ dollars. D is owed $32-28=4$ dollars. E is owed $30-28=2$ dollars. One simple way to resolve this is for C to give E $\$2$, and for B to give A $\$14$ and D $\$4$ dollars.
