A science teacher collects 19 pints of lake water for a lab she is teaching. The lab requires each student to use 4 fluid ounces of lake water. If 44 students are participating, how many pints of lake water will the teacher have left over?

A science teacher collects 19 pints of lake water for a lab she is teaching. The lab requires each student to use 4 fluid ounces of lake water.

If 44 students are participating, how many pints of lake water will the teacher have left over?

There will be pints of lake water left over.

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.
