For the first phase of the project, imagine you want to cover the backyard with decorative rock, drought tolerant plants, and trees. You need 18 tons of rock to cover the area and want to purchase 20 plants. If each ton of rock costs $70, each plant is $20, and each tree is $74, what is the maximum number of trees you can buy with a budget of $2,500? Write an inequality that illustrates the problem and solve.
