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

Answer:
1996 and 2000
Step-by-step explanation:
Since P (the population) is represented in thousands, 8000 will be represented by 8.
Plug in 8 as P and solve for t:
P = 2|t - 8| + 4
8 = 2|t - 8| + 4
4 = 2|t - 8|
2 = |t - 8|
Separate this into 2 possible cases:
2 = t - 8 and -2 = t - 8
Solve:
2 = t - 8
10 = t
-2 = t - 8
6 = t
So, the answers are 6 and 10.
The town will have a population of 8000 in 1996 and 2000
