Systems of Linear Equations: Two Variables · Exercise 75
Use a system of linear equations with two variables and two equations to solve.
An investor invested 1.1 million dollars into two land investments. On the first investment, Swan Peak, her return was a 110% increase on the money she invested. On the second investment, Riverside Community, she earned 50% over what she invested. If she earned $1 million in profits, how much did she invest in each of the land deals?
