Huey works 175 hours each month and earns $14.25 per hour after taxes. His monthly budget is shown. How much money is left over in his budget for unplanned expenses?

For this case we have the following equation:
 y = 14.25x
 Where,
 x: number of hours
 y: total salary
 For x = 175 we have:
 y = 14.25 * (175)
 y = 2493.75
 The amount of money for unexpected expenses is:
 unplanned expenses = 2493.75 - 1250 - 200 - 350 - 400 - 225 - 300
 unplanned expenses = -231.25 <0
 We note that there is no money left for unexpected expenses
 Answer:
 there is nothing left over
