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.)

Respuesta :

If you add the 20% to the $94.20 you will get $113.04 after that you subtract the 15%
 

5).20x94.20=18.84+94.2=113.04+16.96=(96.08)
