Asked by Jane erring

you invest 2500 in the stock market for one year. part of your investment was in stock that paid 10% interest and the remainders was in a stock that paid only 8%. if you made a total of 2,200 in interest how much did you invest in each stock

if x at 10%, then the rest (2500-x) at 8%. So, add up the interest:

.10x + .08(2500-x) = 2200
