Q: Federal guidelines recommend eating at least 2 cups of vegetables per day. From breakfast on Sunday to the end of the day on Thursday, Sarah has eaten 8 cups. How many cups per day does Sarah need to eat of her vegetables in order to meet her daily minimum requirement for the week?
A: There are 7 days in a week and 2 cups are recommended per day, bringing the total to 7 days * 2 cups / day = 14 cups for the week. Out of the 14 total cups needed for the week, Sarah has already eaten 8, for a total of 14 cups - 8 cups = 6 cups left to consume for the week. Sunday through Thursday equals 5 days that have passed. If there are 7 days in the week then Sarah has 7 days - 5 days = 2 days left of the week. If she needs to eat 6 more cups in the next 2 days then she will have to eat 6 cups / 2 days = 3 cups per day over the next two days. The answer is 3.
