Question 344549: I am having serous trouble with writing equations. Please help me with this one?
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

You can put this solution on YOUR website!
TotalCost+=+CostOfRocks+%2B+CostOfTrees
A ton of rocks costs $60 and you need 30 tons of rock. So CostOFRocks+=+60%2A30+=+1800
CostOfTrees+=+t+%2A+84
TotalCost+%3C=+2500
2500+%3C=+1800+%2B+84t
700+%3C=+84t
8.33+%3C+t
Since you can't buy less than a full tree, you can plant 8 or fewer tress and still be within the budget
