The invested amount dogwood tree is $15000 and on maple tree is $45000 as per linear equation.
What is a linear equation?
"A linear equation is an equation in which the highest power of the variable is always 1. It is also known as a one-degree equation. When this equation is graphed, it always results in a straight line."
Given, total invested amount is $60000.
Let, invested amount for dogwood trees is $x.
Therefore, invested amount for maple trees is ($60000 - x).
Now, the profit on a dogwood tree is 29% = 0.29.
The profit on a red maple tree is 17% = 0.17.
Again, the profit for the entire stock is 20%. = 0.20.
Therefore,
(x + x × 0.29) + [(60000 - x) + (60000 - x) × 0.17 = 60000 + 60000 × 0.20
⇒ 1.29x + 60000 - x + 10200 - 0.17x = 72000
⇒ 0.12x = 72000 - 60000 - 10200
⇒ 0.12 x = 1800
⇒ x = 15000
Therefore, invested amount on dogwood tree is $15000.
Similarly, invested amount on maple tree is $(60000 - 15000) = $ 45000.
