6 books at $ 8 = (6 * 8) = 48
if he got a discount of 20%, then he paid 80%
0.80(48) = 38.40 <== what he paid
2880 books
Divide 1920 by 40
Then multiply the number by 2
You will get 96
Then multiply it by 30
Factors of 56 are: 1, 2, 4, 7, 8, 14, 28, 56
<span>Factors of 84 are: 1, 2, 3, 4, 6, 7, 12, 14, 21, </span>28, 42, 84
The outside term multiplies by the outside term on the oposite side to equal the answer.
Example:
Look at the factors of 84
84X1=84
2X42=84
3X28=84
and so on!
