Sargent Park 8-17 Math

Thursday, January 12, 2006

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
+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
