You can work no more than 60 hours each week at your two jobs. Dog walking pays $7 per hour and your sales job at Computers & More, Inc. pays $12 per hour. You need to earn at least $450 each week to pay your bills. Your friend solves the system of inequalities {x+y≤60

{7x+12y≥450

and tells you that a possible solution is (-3, 50). Is this a possible solution, why or why not?

Yes it can be a possible answer because if you take 12x50 you will get 600, then you have to subtract the - 21 from the (7x-3) an you will have $579.
