<h3>
Answer: $10.45 (choice C)</h3>
Work Shown:
20% = 20/100 = 0.20
20% of 52.25 = 0.20*52.25 = 10.45
side note: The total cost, including the tip, is 52.25+10.45 = 62.70 dollars
I guess you want the roots of the equation.
We can factor that as
(x-6) * (x + 10)
The roots of the equation are
6 and -10
