Answer:
$11.50. Each CD cost $11.50.
Step-by-step explanation:
When trying to determine how much each CD cost, we need to know our total cost, $57.50, and how many CDs were bought, 5.
Since 5 CDs cost $57.50, we can divide our total cost by the number of CDs purchased to find the cost of each CD. 57.50 / 5 = 11.50
What is the opposite of multiply? division. 63÷9=7
7 is your answer
So it is essentially 80% of the original price , so what i would do is divide it by 8 and then times it by 10 to get the original price , in this case it will be 50/8 (6.25) and then times 6.25 by 10 which will give you the original price of $62.50<span />
