For the first phase of the project, imagine you want to cover the backyard with decorative rock and plant some trees. You need 30 tons of rock to cover the area. If each ton costs $60 and each tree is $84, 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. Express your answer as an inequality and explain how you arrived at your answer.

Would 5 be a solution to the inequality? Justify your answer.

    Five is not the answer.

    You need to spend 30x60 = $1800 on rocks. That leaves you with $700 for trees.
    The maximum number of trees you can buy is the largest integer x that satsifies
    84 x <or= 1500

    x = 17

    What is wrong with my math?

    700 / 84 = 8.33

    Ms Sue is right. I don't know where the 1500 number came from. My mind was wandering
