Question

You have ​$19,000 to​ invest, part at 6% and the rest at 7%. If x is the amount invested at 6 %6%​, write an algebraic expression that represents the total annual income from both investments. Simplify the expression.

Answer 1

total annual income = 1330 - 0.01x

Step-by-step explanation:

given data

invest = $19,000

some part at = 6%

remaining part = 7%

x is amount invested at = 6 %

solution

we know x part invested = 6 %

so ( $19,000 - x ) part invested = 7 %

so we get here total annual income from both investment that is

income = 6% x + ( 19000 -x ) 7%

so total annual income = 0.06x + ( 19000 -x) 0.07

total annual income = 1330 - 0.01x
