Question

Whitney already owns 10 hair bands, and additional hair bands are priced at 1 for a dollar.

How much money does Whitney need to spend on new hair bands in order to own a total of
22 hair bands?

Answer 1

11 hair bands.

Explanation: Each hair band is priced at a dollar. She wants 22 hair bands and she already has 10. 10 + 12 = 22.

Answer 2

22 ( total) - 10 ( what she has already) = 12 ( the amount she needs to buy)

If 1 hair and = $1
Than 12 multiplied by $1 = $12

So she needs to spend $12 in order to have 22 hair bands
