Question

PLEASE HELP!

Answer 1

We know for the problem that the performer earned $120 at a performance where 8 people attend. We also know that he uses 43% of the money earned to pay the costs involved in putting on each performance, so we need to find the 43% of $120. To do that, we are going to divide 43% by 100%, and then multiply it by $120:
$\frac{43}{100}*120=51.6$
Now we know that the performer uses $51.6 of $120 to pay the costs involved in putting on each performance. The only thing left to find his profits is subtract $51.6 from $120:
$120-51.6=68.4$

We can conclude that the performer makes a profit of $68.4 when 8 people attend his performance.
