Question

jill works two jobs to pay for college. she tutors for $15 per hour and also works as a cashier for $8 per hour. due to her class and study schedule, jill is only able to work up to 20 hors per week, but must earn atleast $150 per week. if t represents the number of hours jill tutors and c represents the number of hours she works as a cashier, write a system of equations for this scenario.

Answer 1

she makes $15/hr tutoring for t hours per week = 15t tutoring income
she makes $8/hr cashiering for c hours per week = 8c cashiering income

total income = sum of those two
total income >= $150

total hours worked = t + c
total hours <= 20

that's the framework, can you expand the equations?
