Question

You can work at most 20 hours next week. You need to earn at least $130 to cover your weekly expenses. Your pizza delivery job pays $10.50 per hour and your job as a car wash attendant pays $7.50 per hour. Write a system of linear inequalities to model the situation.

Answer 1

P = # of hrs at pizza delivery job, c = # of hrs at car wash job
p + c < = 20 (thats less then or equal)
10.50p + 7.50c > = 130 (thats greater then or equal)
