Glenda and Fiero are at a restaurant eating 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? (I ALREADY KNOW THE ANSWER. BUT I NEED THE WORK FOR THE ANSWER TO SHOW MY TEACHER) (the answer is $29.16))

Respuesta :

The cost of meal = [tex]$30[/tex]

The tip to the waiter = [tex]8%[/tex]%

Discount = [tex]10%[/tex]%

Cost = [tex]30 + 0.08 * 30 - 0.1 * 30[/tex]

Cost = [tex]30(1 + 0.08 - 0.1)[/tex]

Cost = $[tex]$29.4[/tex]0
