Answer:
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
28+(140-56)/6-(80-39)
=28+84/6-41
=28+14-41
=42-41
=1
