Q:
# Joanne works two jobs to pay for college. She tutors for $25 per hour and also works as a receptionist for $12 per hour. Due to her class and study schedule, Joanne is only able to work up to 25 hours per week but must earn at least $200 per week. If t represents the number of hours Joanne tutors and r represents the number of hours she works as a receptionist, which system of inequalities represents this scenario? t + r greater than or equal to 25 25t + 12r = 200 t + r less than or equal to 25 25t + 12r less than or equal to 200 t + r less than or equal to 25 25t + 12r greater than or equal to 200 None of the systems shown represent this scenario

Accepted Solution

A:

The correct option is C:

"t + r <= 25

25t + 12r >= 200"

Because t+R cannot be more than 25 hrs and 25t+12r can be great or equal to $200 because it says she makes at least 200

"t + r <= 25

25t + 12r >= 200"

Because t+R cannot be more than 25 hrs and 25t+12r can be great or equal to $200 because it says she makes at least 200
