Question

Which is better to buy, 6 CD's for $12 or 8 CD's for $14.50?

Answer 1

8 CDs for $14.50

Explanation:

We have to divide both of the numbers by the number of CDs. Our formula is:

(price) ÷ (number of CDs) = price per CD

When we divide both of the prices by the number of CDs, we see that 6 CDs for 12.00 is worse because it is 2.00, whereas the inflation is lower when you compare to the other rate. You get $1.81.
