Question

a city league team scores an average of 86 points a game. the coach wants a 20% increase in points for the following year. how many points must team score per game on average to meet this goal?

Answer 1

Let:

A = Average points = 86

N = Points team must score per game on average next year

r = increase in points for the following year = 20% = 0.2

So:

$\begin{gathered} N=A+0.2A \\ N=86+0.2\cdot86 \\ N=86+17.2=103.2 \end{gathered}$
