Anursery has $40,000 of inventory in dogwood trees and red maple trees. the profit on a dogwood tree is 27% and the profit on a red maple tree is 19%. the profit for the entire stock is 20%. how much was invested in each type of tree?

The amount invested in the dogwood tree was $5000, while $35000 was invested in the red maple tree.

We arrive at the answer as follows:

Let the proportion of dogwood trees be x.

Then the proportion of red maple trees in the nursery will be 1-x, since there are only two types of trees in the nursery.

We use the following formula to find the proportion dogwood and maple trees in the nursery:

Solving for x we get

We can find the proportion of maple trees as follows:

Since we have the proportions, we can easily find the amount invested in type of tree as follows:
