Question

Pop Music’s Greatest Hits just came out through Amazon. Each CD costs $12.00, but the same CD can be found on eBay for 75% of the cost. How much can one buy the CD for through eBay?

Answer 1

$9

Explanation:

Multiply by the percentage as a decimal. 75% is the same as multiplying a number by 0.75. For example, 75% of 100 (which is 75) is the same as 0.75 multiplied by 100 (which is also 75).

`12.00*0.75 = 9`, so the CD Can be bought on eBay for $9.
