Use operations of decimal, fraction, and percent numbers to model the following scenarios. In your final answer, include only an equation or proportion modeling the scenario. Do not solve the problems.

5. A family dines in a popular franchise restaurant that has a policy of automatically including a 20% tip on all food and beverage sales before coupon discounts are applied. What is the family’s total bill amount if their food and beverages totaled $94.20 and they used a 15% off coupon? (HINT: Create more than one model.)

What have you been able to do so far?  Even if your first efforts are not correct, I'd be more willing to help you if you first do some work and share it here.

0.15(94.20) = 14.13
94.20 - 14.13 = 80.07
I thought I was correct but my teacher said there is more equations I need to do.

Perhaps you ARE correct, but you have developed only one model, whereas the question asks for two or several models.

mathmale · Answer

I don't see that you have included a 20% tip.

What did the family spend?
How much was the 20% tip?
What was the total of the meal cost and the 20% tip?
Of what do you take 15% off?
Instead of "15% off," you might want to multiply the sum due by (1.00-0.15), which reduces the amount due by 15% a bit faster.
