A company specializing in magazine sales over the phone found that in 2500 calls, 360 resulted in sales and were made by male callers, and 480 resulted in sales and were made by female callers. If the company gets twice as many sales per call with a females voice than with a males, then how many of the 2500 calls were made by females?

1000 calls were made by female callers. Because if you set up a ratio of male calls to female --- 360/480 and then muliply that by 2 because males need twice as many calls to get the most sales, the ratio is 1.5
Therefor the males called 1.5 times more then the females or 1500.
That leaves 1000 calls for the females
The next answer by catbarf would be right but there is an error in the second to last line. Besides for that the equations are right

Let x be calls by females
Let 2500-x be calls by males.
Then 480/x = 2 * (360)/(2500-x)
480(2500-x)=720x
1.2*106 = 1600x
So x=750 and 2500-x=1750
so why do you have so many men working?
