You have $23 comma 000 to invest, part at 8 % and the rest at 9 %. if x is the amount invested at 8 %, write an algebraic expression that represents the total annual income from both investments. simplify the expression.

x = amount invested at 8 %. Then 23 000 - x = amount invested at 9 %

Annual income (I) = interest at 8 % + interest at 9 %

I = 0.08x + 0.09(23 000 – x)

I = 0.08x + 2070 – 0.09x

I = 2070 – 0.01x

4.08%
