Answer:total profit is $8200.
Percentage of profit is 16.4℅
Step-by-step explanation:
Let x represent the total profit.
Total amount invested in company A is $40000. The profit made from this investment is 15% of 40000. It becomes
15/100 × 40000 = 6000
Total amount invested in company B is $10000. The profit made from this investment is 22% of 10000. It becomes
22/100 × 10000 = 2200
The total profit would be 6000 + 2200 = $8200
Total amount of money 40000 + 10000 = 50000
The percentage of the total profit on the total amount invested is
8200/50000 × 100 = 16.4%
