Final answer:
The total profit from both Company A and Company B is $4,880. The percent profit for the investment firm's total investment is approximately 15.25%.
Step-by-step explanation:
To calculate the investment firm's total profit from Company A and Company B, we need to apply the percentage profit for each investment and then sum the amounts.
Profit from Company A
Investment: $20,000
Profit percentage: 16%
Profit = Investment × Profit percentage
Profit from Company A = $20,000 × 0.16 = $3,200
Profit from Company B
Investment: $12,000
Profit percentage: 14%
Profit = Investment × Profit percentage
Profit from Company B = $12,000 × 0.14 = $1,680
Total profit = Profit from Company A + Profit from Company B
Total profit = $3,200 + $1,680 = $4,880
Percent Profit for Total Investment
Total investment = Investment in Company A + Investment in Company B
Total investment = $20,000 + $12,000 = $32,000
Percent profit = (Total profit / Total investment) × 100%
Percent profit = ($4,880 / $32,000) × 100% ≈ 15.25%
