shtirl [24]2 years ago
6 0

Given: {x}^{2} - 7x + 7y -  {y}^{2}

Now factoring them,

=  > (x - y)(x + y) - 7(x - y)

=  > (x - y)(x + y - 7)

Therefore, the answer to the question is (x - y)(x + y - 7)

We know for the problem that the performer earned $120 at a performance where 8 people attend. We also know that he u<span>ses 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:
</span>\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.
