Sketch a supply curve graph illustrating a studentâ€™s willingness to offer tutoring services. î‰e student, call her Lena, is willing to tutor for three hours per week if she receives $10/hour. If Lena receives $15 per hour, she is willing to tutor for five hours per week. If she can charge $20 per hour, she would tutor for seven hours per week. Lastly, if Lena receives $25 per hour, she is willing to tutor for nine hours per week. Carefully label the vertical and horizontal axes. Then describe one situation that would increase Lenaâ€™s supply of tutoring services, and one situation that would decrease Lenaâ€™s tutoring supply.
