Q 1 - Bill took his family out to dinner. He wanted to give the waiter a 15% tip. If the total amount of the dinner was $58, what should be paid to the waiter as a tip? ### Answer : C ### Explanation Step 1: Bill amount =$58

First to get 10% of $58.00, we move decimal one place to left and get$5.80

Step 2:

5% is half of 10%. So 5% of $58 =$\frac{\$5.80}{2} = \$2.90$Step 3: So, 15% of$58 = 10% of $58 + 5% of$58

= $5.80 +$ 2.90 = $8.70 Q 2 - Some ladies went out to a restaurant to celebrate a birthday. The total bill came to$240 of which $15.00 was tax. They decided to leave a 10% tip. How much of a tip should they leave for the waiter? ### Answer : A ### Explanation Step 1: Bill amount before tax =$240 − $15 =$225.00

Step 2:

To get 10% of $225.00, we shift decimal one place to left to get the tip as$22.50

Tip for waiter = 10% of $225.00 =$22.50

Q 3 - Maggie went to a beauty salon to get her hair cut and styled. Her bill came to $115.00. How much did Maggie tip her hairdresser, if she gave 20% tip? ### Answer : B ### Explanation Step 1: Bill amount =$115

Tip = 20% of $115.00 Step 2: First to get 10% of$115.00, we move the decimal one place to the left to get $11.50 Step 3: To get 20% we double this amount as 20 = 2 × 10 So 20% of$115 = 2 × $11.50 =$23.00

So tip amount = $23.0 Q 4 - You go out to eat with friends and your bill was$88. If you tip the waiter 15%, how much amount is paid as tip?

### Explanation

Step 1:

Bill amount = $88; For 10% of$88.00, we move decimal one place to left and get $8.80; Step 2: 5% of$88 = $\frac{\$8.80}{2} = \$4.40$

Step 3:

15% of $88 = 10% of$88 + 5% of $88 =$8.80 + $4.40 =$13.20

So tip amount = $13.20 Q 5 - Mr. & Mrs. Smith hired movers to shift their household items to their new home. They were billed$650 for the work. If they decided to give 10% tip to the movers, how much would the movers receive for a tip?
