Final answer:
To buy the same amount of CDs at the local store and the online store, you can buy 3 CDs at each store.
Step-by-step explanation:
To find the number of CDs that can be bought for the same amount at the two stores, we need to compare the prices per CD at each store. At the local store, each CD costs $15.49. At the online store, each CD costs $13.99 plus $6 for shipping. Let's calculate the number of CDs that can be bought for $56.75 at each store:
Local store:
$56.75 ÷ $15.49 = 3.67 CDs
Online store:
First, subtract the shipping cost from the total amount: $56.75 - $6 = $50.75
Then, calculate the number of CDs that can be bought for $50.75:
$50.75 ÷ $13.99 = 3.63 CDs
Therefore, you can buy 3 CDs for the same amount at both stores. However, since you cannot buy a fraction of a CD, the number of CDs that can be bought is 3 at both stores.
