23. ECONOMICS In 2000, the demand for nurses was 2,000,000, while the supply was only 1,890,000. The projected demand for nurses in 2020 is 2,810,414, while the supply is
only projected to be 2,001,998.
a. Define the variables, and write equations to represent these situations.
b. Use substitution to determine during which year the supply of nurses was equal to
the demand.
