Question 974927: Marcus is working at a local pizzeria where he makes $12.50 per hour and is also working at the university bookstore where he makes $9.50 per hour. He must make at least $300 per week to cover his expenses but cannot work more than 30 hours per week in order to attend classes. Write a system of inequalities that models this situation where p represents the hours he works at the pizzeria and b represents the hours he works at the bookstore.

p for hours at Pizzeria, b for hours at Bookstore.

Restriction to 30 hours per week:
p%2Bb%3C=30

Account for income and needed money:
12.5p%2B9.5b%3E=300

system%28p%2Bb%3C=30%2C12.5p%2B9.5b%3E=300%29
The system of equations which represents the situation.
