Answer: Divide the sale price by the percentage amount that was paid.
Step-by-step explanation:
If a book is on sale for $6.30 with a 30% discount it means that you paid 70% of the original cost. In order to determine what the original cost was you can divide the sale price by the percentage that was paid:
$6.30 / .7 = $9.00, which is the original price of the book.
You can then double check your work - $9 x 70% = $6.30.
A = -0.7
B = -9/16 (0.5623)
C = -0.4
D = -5/16 (0.3125)
The last option is correct
If 100 cats killed 100 mice in 100 days, you can say that each cat killed one mouse the day after the last cat. So, if four cats killed four mice, and we're going of off the same basis that each cat killed one mouse the day after the last cat, then the answer would be 4.
6(2k-3) is the answer to this problem.
make a distributive
take the 6 out of the equation and u have remaining 2k-3. 6(2k-3)
