Answer:

x = 8

Step-by-step explanation:

2logx=log64\\logx^2=log64

now that both sides has log, you can remove them and leave it as:

x^{2} =64\\

take the square root of both sides:

x = [8, -8]\\x = 8

logarithmic equations can't have negative solutions, plus -8 isn't an option

i hope this helped!

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.
