Andrew and his cousin Leah are picking apples in their grandparents' orchard. Andrew has filled 15 baskets with apples and is filling them at a rate of 2 baskets per hour. Leah has 5 full baskets and will continue picking at 3 baskets per hour. Once the cousins get to the point where they have filled the same number of baskets, they will carry them to the barn and then eat lunch. How long will that take? Write a system of equations, graph them, and type the solution.
