9 pints

Step-by-step explanation:

This is a unit question. Okay, we would be needing some conversions here. The most important to know first is how many ounces are in a pint.

It had been established that 1 pint contains 16 fluid ounces. This conversion will aid out calculations.

She collects 20 pints. This means she collected 20 * 16 ounces = 320 ounces

Each student is to use 4 fluid ounces and we have 44 students. The total number of ounces required by the students is simply 4 * 44 = 176 ounces

The amount in ounces left over would be 320 - 176 = 144 ounces

We are asked to get the number of pints left. Hence we need to know the number of pints equivalent to 144 ounces. This is equivalent to 144/16 = 9 pints
