A company made $4 million in the second quarter. This is 1/3 more than it made in the first quarter and 4/5 of what it made in the third quarter. How much did the company make in the three quarters combined?

math 
Reiny,
1st: (4/3)x = 4mill, x = 3 million
3rd: (4/5)y = 4 million , y = 5 million
they made 3 mill + 4 mill + 5 mill = 12 million
