A student earns 15 per hour for tutoring and 6 per hour as a

A student earns $15 per hour for tutoring and $6 per hour as a teacher\'s aide. Let x = the number of hours each week spent tutoring and y = the number of hours each week spent as a teacher\'s aide. Complete parts (a) through (e). a. Write the objective function that describes total weekly earnings. z = 15x + 6y (Do not include the $ symbol in your answer.) b. The student is bound by three constraints. Write an inequality for each constraint. To have enough time for studies, the student can work no more than 21 hours per week.

Solution

student earns $15 per hour for tuetoring x hours,$6 per hour as teacher\'s aid for y hours

(a)

ojective function:

weekly earnings,z=15x +6y

(b)

1)

student cannot work more than 21 hours per week

so

x+y 21
