Work Step by Step
Kawana's description matches graph d. Kawana works 40 hours per week during the summer and slowly cuts back her hours until she does not work at all during the school year. Graph d shows that the y-coordinate (corresponding to hours worked per week) is 40 until August, when it decreases to 0 at the beginning of September. Also, Kawana starts working again during the holiday season and increases her hours to 60 per week. Graph d shows that the y-coordinate begins increasing in December and increases until it reaches 60.
