Suppose you want to cover the backyard with decorative rock and plant some trees as the first phase of the project. You need 30 tons of rock to cover the area. If each ton cost $60 and each tree is $84, what is the maximum number of trees you can buy with a budget for rock and trees of $2,500? Write an inequality that illustrates the problem and solve. Express your answer as an inequality and explain how you arrived at your answer

30 tons of rock x 60 dollars = _____ dollars?

Subract that from 2500 to see how much is left over, then divide by 84 to see how many trees can be purchased.

You will need to decide how to write an inequality, but this seems like a very straightforward problem.
