If 480 students would eat the food in 16 weeks,
Find the number of "food-days" available

but after two weeks, 80 students join, how long will it take them to finish the remaining food?
Find number of food-days remaining after two weeks
53760 - (480*14) = 47040
Find how many days this will last with the additional students:
= 84 days of food which is 84/7 = 12 weeks
