1.
If Jeff makes $5 per hour, then after 5 hours he makes 5x dollars and we are told that $7.50 is a one-time start fee:
So the answer is $5x+$7.50

2.
Plan A--------3x+4y=amount you would pay under Plan A
Plan B--------5x+8y=amount you would pay under Plan B

3.
Waitress-----32+.7x dollars
Cook---------50+.3x dollars

Hope this helps----ptaylor
