There will be ________ pints of lake water left over.

Respuesta :

Answer: 8 pints of lake water

Step-by-step explanation:

We should note that:

1 pint = 16 fluid ounces

Therefore, 19 pints will be converted to ounces which will be:

= 19 × 16

= 304 ounces

Since there are 44 students participating and each student uses 4 fluid ounces, the students will use:

= 44 × 4

= 176 fluid ounces

We then subtract from the total ounces to know the amount left. This will be:

= 304 - 176

= 128 fluid ounces

We then convert back to pints which I'll be:

= 128/16

= 8 pints

There'll be 8 pints of lake water left.
