Answer:

Does your response include the following?

Luca did not square the right side of the equation properly.

When the binomial with the radical term is squared, the result still has a radical.

After simplifying, both sides of the equation have to be squared again.

After simplifying, the resulting quadratic trinomial can be solved by factoring.

There are actually two solutions: x = 3 and x = 7.

there was a tax of 8%.

there was a tip of 18%.

3 dollars

Step-by-step explanation:

what is 8% of $37.50?

To find the percent of something, first you need to put the percent as a decimal.
