The equation that best represent the actual prices of the skis is, I x - 500 I ≥ 250 Solving the absolute value equation, x ≤ 750 and x ≥ 250 Thus, the prices of the skis ranges from 250 to 750.
You can represent Morgan's scenario with the expression, 25w + 615, and you can represent Kendall's scenario with the expression, 15w + 975. To find out when they both have the same amount of money in their accounts, you set them equal to each other and solve for w:
25w + 615 = 15w + 975
25w = 15w + 360
10w = 360
w = 36
Morgan and Kendall will have the same amount of money after 36 weeks.
