Answer:
500 +125x -65y Greater than or equal to 700
Step-by-step explanation:
He already has $500. He then adds $125 for each week he goes to work. We do not know how many weeks he will go to work so that number will be represented with a variable. He then spends, or subtracts 65 for every week he gets groceries and goes to his friends. We also do not know how many weeks he gets groceries and hangs out with his friends so that can be represented with a different variable. He wants to have $700 or more by the end of the summer, so that number needs to be bigger than what he has at the end of summer or equal right to it.
