Elizabeth earns $ x daily and spends $ y per week. What are her savings of 2 weeks?


Answer:

14x - 2y

Step by Step Explanation:
  1. Number of days in one week = 7 days
    Therefore, the number of days in 2 weeks = 2 × 7
    = 14 days
  2. Amount earned by Elizabeth in one day = $ x
    Therefore, the amount earned by her in 2 weeks, or 14 days = $ 14x
  3. Amount spent by Elizabeth in one week = $ y
    Therefore, the amount spent by her in 2 weeks = $ 2y
  4. Thus, Elizabeth's 2 weeks saving = Amount earned in 2 weeks - Amount spent in 2 weeks
    = $ 14x - $ 2y
