Lincoln Norris bought 3 boxes of cereal at $3.79 each, a roll of paper towels for $1.78 , and 2 pounds of margarine at $1.28 a pound .How much change would Norris get back from $20.00 if there was no sales tax?

Answer 1

Amount of money Lincoln Norris will receive back is $4.79.

Explanation:

Given:

Total Money Given = $20.00

Number of Cereal boxes = 3

Cost of Each Cereal box = $3.79

Cost of 3 Cereal box = how much is the price

By using Unitary method we get:

Cost of 3 Cereal box =
`3.79*3 = \$11.37`

Also Given:

Cost of Roll of Paper towel = $1.78

Amount of Margarine = 2 pounds.

Cost of 1 pound of Margarine = $1.28

By using Unitary method we get:

Cost of 2 pound of Margarine =
`1.28*2 = \$2.56`

Total Shopping done = Cost of 3 Cereal box + Cost of Roll of Paper towel + Cost of 2 pound of Margarine = $11.37 + $1.28 +$2.56 = $15.21

Now Money she will received back is equal to total money gave minus total shopping done.

Amount of money she received back =
`\$20-\$15.21=\$4.79`

Hence, Amount of money Lincoln Norris will receive back is $4.79.
