Question

Glenda and Fiero are at a restaurant eating a meal that costs $30. They have a discount coupon that gets them 10% off the cost. If they pay the waiter a tip of 8% of their bill, how much are they spending on dinner including tip?

Answer 1

The cost of meal = $30
The tip to the waiter = 8%
Discount = 10%

Cost = 30 + 0.08 x 30 - 0.1 x 30
Cost = 30(1 + 0.08 - 0.1)
Cost = $29.4
