Respuesta :

Answer: $9.20

Step-by-step explanation: To get the answer, you add both the cost and multiply it by .15. Then you add the product to the number you got adding the cost of the food.

Answer:

$1.20

Step-by-step explanation:

He has to leave 100% of the cost which is $5.50 + 2.50 or $8.00.

He wants to leave 115% of the $8 he has to leave.

So you set it up like

x/8 = 115/100

Then you solve for x

8(115) = 920

920/100 =9.2

So he will leave $9.20.

It then asks for just how much the tip is that he will leave so

9.2 - 8 = 1.2

So the tip is $1.20.
