After Sam spent 5/7 of his money and Nora spent 7/8 of her money, Sam had \$13.50 more than Nora left. How much did they have altogether at first? My work Amount for Nora = N Amount for Sam = S [1] We know that Sam and Nora had the same amount: N = S [2] We know Sam spent 5/7 of his money and Nora spent 7/8 of her money, and after, Sam had \$13.50 more than Nora: 5/7S + 13.50 = 7/8N Since we know N = S, I replaced N from the [2] with S. So, 13.50 = 7/8S - 5/7S S = 84, N = 84 Answer 168 Is my work mathematically correct? Last edited by skipjack; September 18th, 2018 at 01:38 AM.
