a business man invested 10000 in two different business A and B.A gave total returns of 8%and B 15%. if he had total gain of 4500,how much did he invest in each business
Answer provided by our tutors
let
a = the money invested in business A, a>0
b = the money invested in business B, b>0
a business man invested 100000 in two different business A and B:
a + b = 100000
he had total gain of 4500:
0.08a + 0.15b = 4500
by solving the system of equations:
a + b = 100000
0.08a + 0.15b = 4500
we find:
a = - 42,857.1429
b = 52,857.1429

We got a negative solution for a meaning the investment of business A which contradicts with a > 0.
Thus the problem has no solutions.
