1. Oak Hill, Longview, and Peabody Schools participated in a clean-up campaign to collect scrap aluminum. Oak Hill School collected 40% more scrap aluminum than Longview School. Longview School collected 25% more than Peabody School. If the total collected by the 3 schools was 560 kg, how much did Oak Hill School collect?

2. Eladio invested 200$ at 6% annual interest and 350$ at 5.75 annual interest, both compounded annually. If he makes no deposists or withdrawals, how much will he have after two years?
