Question

At a camp, there is sufficient food for 54 scouts for 7 days. If 9 more scouts join the camp, how long will the food last?​

Answer 1

Answer:

6 days

Step-by-step explanation:

(it is in inverse variation, as when the number of scouts increase, the number of days the food lasts decreases)

scouts days

54          7

54+9     x

scouts days

54        7

63      x

x = 54*7/63

x = 378/63

x = 6
