Question

The 15 students on the swim team want to raise$284.20 to buy practice suits. They have alreadyraised $58.75. If each student raises the sameamount, how much more money must each studentraise?

Answer 1

Let's define the next variable

x: the amount of money each student has to raise

If 1 student raises x dollars, then 15 students will raise 15x dollars.

They want to raise $284.20 and they have already raised $58.75, therefore they need:

$284.20 - $58.75 = $225.45

Combining this information, we get:

$\begin{gathered} 15x=225.45 \\ \frac{15x}{15}=\frac{225.45}{15} \\ x=15.03 \end{gathered}$

Each student has to raise $15.03
