Math Word Problem......retirement problem?? Don't Understand!?

Question

Alisa has a retirement account valued at $200,000. She would like to earn $25,000 per year. If she invested $80,000 at a 9.5% account. What rate should she earn in the remainder to achieve her goal?

Answer 1

Find how much she would make on the 80 K (80Kx.095). Subtract it from 25K.

With the 80 K gone she has 120K left.
120K x N=Whatever you got when you subtracted 25K.
I'm not going to fully do your homework, but I think you can get it from there.

Answer 2

80,000 x 9.5% + (200,000 – 80,000) x r = 25,000
7600 + 120,000 x r = 25,000

120,000 x r = 17400
r = 14.5 %

She should earn 14.5% in the remainder to achieve her goal.
