The Martinez family goes out to lunch, and the price of their meal is $45. The sales tax is 6%, and the family intends to leave a 20% tip. How much will their meal cost total, including both tax and tip? (Note: The tip and the tax are both based on the original price of the meal, $45)

hello from mrbilldoesmath!

answer:

x - 3

discussion:

x^2 - 9 = (x-3) (x+3)   so

mrb
