A book is marked 20% off. What percent of the original price is the sales price? (What percent do you still have to pay for?) If the original price is $55, how much will the sales price be? If the sales price rings up as $46.60, what was the original price?

1. 80%

2. $44

3. 58.25

Step-by-step explanation:

If a book is 20% off then it will still have 80% that you have to pay for because the highest possible percentage is 100% and 100-20 is 80.

Percents can also be represented as decimals.

20% -> .20 80%->.80

There are two ways you can solve the next question.

55 - 55(.20) = 44

55(.80) = 44

If $46.60 is the sales price then it is .80 of the original price.

This can be written as an algebraic formula.

Let x be the unknown total price.

.80*x = 46.60

x = 46.60 ÷ (.80) = 58.25

You could also realize that .80=80/100=4/5. So divide 46.60 by 4 and multiply that by 5.

46.60÷4=11.65

11.65*5=58.25

8

step-by-step explanation:

to find the amount of gift bags to use all the supplies, find the gcf or greatest common factor. this is the largest number which multiplies evenly into each term.

48 has factors: 1, 2, 3, 4, 6, 8, 12. 16, 24, 48

80 has factors: 1, 2, 4, 5, 8, 10, 16, 20, 40, 80

64 has factors: 1, 2, 4, 8, 8, 16, 32, 64

the highest number factor they all share in common is 8. this means there will be 8 bags with 6 pencils, 10 markers, and 8 stickers in each bag.
