21. Finance Adrienne invested a total of $1900 in two simple-interest money market accounts. Account A paid 3% annual interest and account B paid 5% annual interest. The total amount of interest she earned after one year was $83. If a represents the amount invested in dollars in account A and b represents the a + b= 1900 amount invested in dollars in account B, the system of equations can represent 0.03a + 0.05b= 83 this situation. How much did Adrienne invest in each account?

Select the system of equations that represents this situation. Use c to represent the cost of a cup of coffee and w to represent the cost of a bottle of water. 6 cups of coffee and 2 bottles of water cost $14. 8 cups of coffee and 1 bottle of water cost $17. A. 6c+ 2w = 14 8c + w = 17 B. 2c + 6w = 14 c+ 8w = 17 C. c+ w = 17 6c + 2w = 14 D. 6c+ 8w = 14 2c+ w = 17

Kelly Fisher has a total of $40,000 invested in two municipal bonds that have yields of 7% (bond A) and 9% (bond B) interest per year, respectively. If the interest Kelly receives from the bonds in a year is $3,440, how much did she invest in each bond? Formulate a system of equations that can be used to find the solution where x is the number of dollars invested in bond A and y is the number of dollars invested in bond B.
