Lizzy: Yasmin deposited a $50 birthday check from her grandmother in her bank account. The check was worth a quarter of her new balance after the check money is added. How many dollars were in her account before she deposited the check?.
Me: Hmmm, let me think. I think this is the detailed solution:
The $50 check is worth 1 / 4 of Yasmin’s new balance, so her new balance is 50 * 4 = $200. Thus, Yasmin had 200 - 50 = $150 in her account before she deposited the check. Final answer: 150.
