<u>ANSWER: </u>

Scott has 6000 points in his fantasy baseball league.

<u>SOLUTION: </u>

Given, Donal currently has 7,200 points in his fantasy baseball league.

It is 20% more points than Scott points.

We need to know how many points does scott have?

Let the points with scott be x.

Then, according to give information

Donal points = scott points + 20% of scott points

$\begin{array}{l}{7200=x+20 \% \times x} \\\\ {7200=x+\frac{20}{100} \times x} \\\\ {7200=x+\frac{1}{5} \times x} \\\\ {7200=x+\frac{x}{5}}\end{array}$
