Answer:

To find a 20 percent tip quickly, first find 10%, and then multiply it by 2.

Step-by-step explanation:

To find 10%, move the decimal 1 place to the left. So 10% of 53.82 is 5.382. Let's round that to 5.4 to simplify. Multiply it by 2 to get to 20% which is 10.8 and round to the nearest dollar to make $11.

SI = PRT /100

1. SI = 400*5*1/100
= 2000/100
= $ 20

2. SI = 1000*8.5*3/100
= 25.5*1000/100
= $ 255

3. SI = 200*9*1/2*100
= 900/100
= $9

4. SI = 20000*12*3/100
= 200*12*3
= 7200

5. SI = 1200*4.5*6/12*100
= 4.5*6
= $27

Amount to pay = Principal + SI
= 1200+27
= $1227 ( But this answer isn't there in the options )
