Sandy has $4,000 invested in stocks and bonds. Last year, she earned 8% interest on the stocks and 6% interest on the bonds. At the end of the year, Sandy received
a check for $270. This was her annual income from the stocks and bonds. Which
system of equations below will determine s, the amount of money Sandy has
invested in stocks, and b, the amount invested in bonds?
F S + b = 4,000
Hs + b = 270
0.08s + 0.06b = 270
4,000
+ b = 270
S
Gs + b = 270
4,000 270 = s
Js + b = 4,000
0.06s + 0.08b = 270
