Eye surgery institute just purchased a new laser machine for 500,000 U.S. dollars for use in eye surgery. The Institute should pay the inventor $ 550 each time the machine is used. If the Institute charges $ 2,000 for each laser surgery, the minimal number of operations has to be there, preformed at the Institute to make a profit?

The Eye Surgery Institute Just Purchased I Need Help Solving This Math Problem..?

Let x = number of operations
2000x - 550x> 500,000
1450x> 500,000
x> 344.8
It must begin at least 345 operations to a profit.
Thus, for each operation of the institute until 1450 (is 2000 - 550)
to 500 000 / 1450 = 344.82,
So we can say 345 times after the start of the Institute receive the benefit.
U.S. $ 500,000 is fixed and the other numbers are variable. You need to do is up to $ 550 to $ 2000, $ 1450, which is then subtracted $ 500,000 $ share from 1450
