A tree house costs $530. You plan to save $10 each week. Your parents will help you pay $80 of the cost. Your savings plan can be modeled with the equation S = 10w + 80. Use a table of values to graph the equation in the first quadrant of the coordinate plane. After how many weeks will you be able to afford the tree house?

• 47 weeks

• 46 weeks

• 45 weeks

• 44 weeks
