1. Sami decided to park her car at Park&Go for her four-day trip. The cost is usually$8 per day or partial day. However, Sami has a 20% discount coupon for her entirebill. How much did Sami’s parking cost?

Answer:

$8 x 4 =32 <-- total payment

Discount: 20% of 32 to get 20 % of 32:

100% = 32

10%=3.2

20%=6.4

so you have to subtract 20% of 32 from the total parking fee:

100%=32

25.6

So, Sami's parking cost is $25.60

Answer:

$8 x 4 =32 <-- total payment

Discount: 20% of 32 to get 20 % of 32:

100% = 32

10%=3.2

__+10%=3.2__20%=6.4

so you have to subtract 20% of 32 from the total parking fee:

100%=32

__- 20%= 6.4__25.6

So, Sami's parking cost is $25.60
