Answer:

Part A: US$ 17

Part B : US$ 102

Step-by-step explanation:

1. Let's check all the information given to us to answer the question correctly:

Dinner bill = US$ 85

Tip to the server = 20% of the bill

2. What’s the tip?

20% = 0.2

Tip to the server = 0.2 * 85

Tip to the server = 17

3. What’s the total of the dinner?

Total of the dinner = Dinner bill + Tip to the server

Total of the dinner = 85 + 17

Total of the dinner = 102
