An investment firm invested in 2 companies last year. They invested 40,000 in company A and made a profit of 15%. They invested company B 10,000 and made profit of 22% How much was total profit and percentage

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%
