Acompany made 4 million in the second quarter this is 1/3 more then it made in the first quarter and 4/5 of what it made in the third quarter how much did the company make in all 3/4 combined

In this problem, you have to find the total profit the company made in the three quarters which makes up 3/4 of the whole. In the second quarter, the profit is 4 million. Let x be the profit in the first quarter. Following the description,

4 = (1+1/3)x
x = 3 million

Thus, the second quarter made 5.33 million profit.

For the third quarter, let's assign it to the y variable. Following the description,

4 = (4/5)(y)
y = 5 million

Thus, the total profit is 4 + 3 + 5 = 12 million
