Question

Shannon had 165 in her baseball collection. She sold 153 of the cards to purchase a new ipod. What is the percent of change in the number of Shannon's baseball collection?

Answer 1

There was a -92.7% change in the number of cards in Shannon's collection.

Explanation:

The percentage change can be calculated using the formula:

`p = (N - O)/O * 100` where `p` is the percentage change, `N` is the New Value and `O` is the Old Value. Substituting for the New Value (`165 - 153 = 12`) and the Old Value (165) we can calculate the percentage change:

`p = (12 - 165)/165 * 100`

`p = (-153)/165*100`

`p = (-15300)/165`

`p = -92.7` rounded to the nearest tenth.
