Suppose that you received an unexpected inheritance of ​$28,800. You have decided to invest the money by placing some of the money in stocks and some in bonds. To​ diversify, you decided that three times the amount in bonds should equal five times the amount invested in stocks. How much should be invested in​ stocks? How much should be invested in​ bonds?

Respuesta :

s is stocks and b is bonds
s + b = 28800
3b = 5s or s = 3/5 b

substitute in for s
3/5 b + b = 28800
3b + 5b = 144000
8b = 144000
b = 18000 amt in bonds

s + 18000 = 28800
s = 10800 amt in stocks
