## Problem 2

Four friends do yardwork for their neighbors over the weekend, earning $15, 20, 25,$ and $40,$ respectively. They decide to split their earnings equally among themselves. In total how much will the friend who earned $40$ give to the others?

$\textbf{(A) }5 \qquad \textbf{(B) }10 \qquad \textbf{(C) }15 \qquad \textbf{(D) }20 \qquad \textbf{(E) }25$

## Solution

First we average $15,20,25,40$ to get $25$. Thus, $40 - 25 = \boxed{\textbf{(C) }15.}$. ~~Spaced_Out

## Solution 2

The total earnings for the four friends is $15+20+25+40=100$. Since they decided to split their earnings equally among themselves, it follows that each person will get $\frac{100}{4}=25$. Since the friend who earned $40$ will need to leave with $25$, he will have to give $40-25=15$ to the others $\implies\boxed{\textbf{(C) }15}$.
