Question

Mr. Gordon wants to bring punch for all 29 students in his class. One bottle of punch is enough for 10 students. How many bottles of punch does he need?

Answer 1

Given:

The number of students, N=29.

One bottle of punch is enough for 10 students.

So, the number of bottles needed for 29 students is,

`n=(N)/(10)=(29)/(10)=2.9`

Since the number of bottles cannot be a decimal number, we approximate 2.9 to 3.

Therefore, 3 bottles is needed to be brought by Gordon for all 29 students.
