For the first phase of the project, imagine you want to cover the backyard with decorative rock and plant some trees. You need 25 tons of rock to cover the area. If each ton costs $62 and each tree is $76, what is the maximum number of trees you can buy with a budget of $2,000? Write an inequality that illustrates the problem and solve. Express your answer as an inequality and explain how you arrived at your answer.

25*62 + 76 n </= 2000

1550 + 76 n </= 2000

76 n </= 450

solve as equality and get n = 5.92
well we can not plant .92 of a tree, so we can not plant more than 5
however we can plant less
so
n </= 5
