for her birthday. Stephanie received $50 from her grandmother and $15 from her aunt. She spent $10.90 each on two CD's, $20.25 on a sweater, and $10.30 at the movies. Estimate how much she had left from her birthday money.​

She had $12.65 left from her birthday money.

Explanation:

Amount of money Stephanie received:
50 + 15 = $65

Amount of money Stephanie spent :
10.90 + 10.90 + 20.25 + 10.30 = $52.35

(10.90 is written two times, because the question says she spent $10.90 each for TWO CD’s. $10.90 for one CD, and another $10.90 for the second CD.)

Amount of money she had left:
65 - 52.35 = $12.65
