A person invested $13,000, part of the money, x, was placed in a stock that paid 9% annual interest. The rest of the money suffered a 5% loss. Express the total annual income from both investments, I, as a function of x.

I=0.14X+12350

Step-by-step explanation:

Amount=$13,000

Profitable Investment,9%=X(1.09)

Negative Investment,-5%=(13,000-X)(1-0.05)

=>I=X(1.09)+(13000-X)(0.95)

I=1.09X-0.95X+12350

I=0.14X+12350
