Question: Jim starts with $80 in his investment portfolio. After 1 year it grows by 15%. He then adds another $28 to his portfolio. After 1 more year the combined portfolio grows by 10%. What is his final portfolio worth after 2 years from when he started? Is final answer 132?
Answer: After 1 year Jim has gained $80 * 0.15 = $<<80*0.15=12>>12
Therefore, after 1 year his portfolio has grown to $80 + $12 = $<<80+12=92>>92
He then adds $28 to this total, so his new portfolio total is $92 + $28 = $<<92+28=120>>120 at the beginning of year 2
Next, this total grows by 10%, so he gains $120 * 0.10 = $<<120*0.10=12>>12 across year 2
Thus, after year 2, his portfolio is worth $120 + $12 = $<<120+12=132>>132
