At one point during the summer, Marsha has read 500 pages of her summer reading assignment, and Juan has read 460 pages.  Marsha reads 20 pages per week for the remainder of the summer, and Juan reads 30 pages per week for the remainder of the summer.  How many weeks, w, will it take before the girls have read the same number of pages?

• 500 + 30w = 460 + 2w
• 30 + 500w = 20 + 460w
• 20 + 500w = 30 + 460w
• 500 + 20w = 460 + 30w
