Question

1. Your parents took your family out to dinner. Your parents wanted to give the waiter a 22% tip. If the bill was $64.85, how much did your parents pay for dinner?

2. Michael took his son to the Magic game. Tickets for both of them cost $140 plus a $3.50 handling fee. He had to pay 6.5% sales tax. How much did Michael pay in total?

Answer 1

1. ROUNDED 64.85 + 14.27 = 79.12

NOT ROUNDED 64.85 + 14.26 = 79.11

2. 143.50 + 9.32 = 152.82 not rounded

143.50 + 9.33 = 152.83 rounded

Explanation:

1.

We need to find 22% of 64.85, and we do that by multiplying

64.85 x 0.22 = 14.267

Now we have 2 choices, if you round, the tip will be 14.27, but if you do not round, it will be 14.26. If you aren't sure, round the answer. 64.85 + 14.27 = 79.12 OR 64.85 + 14.26 = 79.11

2.

We will first solve for the total cost of the tickets before the sales tax

140.00 + 3.50 = 143.50

Then, we will calculate sales tax

143.50 x 0.065 = 9.32 not rounded

143.50 x 0.065 = 9.33 rounded

143.50 + 9.32 = 152.82 not rounded

143.50 + 9.33 = 152.83 rounded
