Lizzy: Todd borrowed $100 from his brother to start a snow-cone stand. He has to repay him $110 as soon as he can. Todd spent $75 on ingredients for the snow cones. He sells 200 of them for $.75 each. After he pays back his brother, how much money does Todd have?.
Me: Hmmm, let me think. I think this is the detailed solution:
Todd has $25 left after buying ingredients because 100 - 75 = 25. Todd made $150 selling snow - cones because 200 x .75 = 150. Todd has $175 before he pays his brother back because 25 + 150 = 175. After Todd pays his brother back he has $65 because 175 - 110 = 65. Final answer: 65.
