1. Erik buys carrots and dip for a class snack. The carrots are $3.80, and the dip is $2.60. Erik has a coupon for 5% off his groceries. He does not need to pay tax. He gives the cashier $20. How much change does he receive back?
2. Liam buys a new TV that cost $360. The TV is on sale for 40% off, and the store is offering an additional 20% off all sale items. How much does Liam save on the TV?

Answer:

1. $3.80 + 2.60=$6.40 *.05=$5.08  

$20.00-$5.08=$14.92

2. $360 x %40=$14,000

$14,000/100=144   360-144 = 216

$216 x %20 = $4,320/$100= $43.20

$216-43.20= $172.8

$360-$172.80=$187.20
