The error done by Wen was during calculating the values of fraction.
So, the correct answer is : instead of
Answer: B
Function 2's rate of change is 3/2, and Fuction 1's rate of change is 2/5
3/2 is bigger than 2/5

The food will last for 25 days with 72 boys
Step-by-step explanation:
Proportions can be used to find the number of days the food will last for 72 boys.
60 boys in a hostel have food for 30 days.
Let x be the number of days for which the food will last
The proportion or product of both scenarios has to be same as the number of days and number of boys are proportional
Which means
Hence,
