^n=1/square root of 59 (535) ,if that makes sense its hard to type it
12.25x + 8.75y > = 90 (thats greater then or equal) <== ur inequality
If you add the 3/4s with the 2 1/4 hour breaks it would be 1 hour and 1 fourth.
Then you take 10-1/2 hours and subtract it by 1 hour and 1 fourth.
So you would get 9-1/4 hours
