A science teacher collects 18 pints of lake water for a lab she is teaching. The lab requires each student to use 4 fluid ounces of lake water. If 52 students are participating, how many pints of lake water will the teacher have left over?

The teacher will have 5 pints left.

Step-by-step explanation:

One pint has 16 fluid ounces, therefore if the teacher got 18 pints he has a total of:

lake water = 18*16 = 288 fluid ounces

If each student use 4 fluid ounces, and there are 52 students the class will use:

used = 52*4 = 208 fluid ounces

And the remainder will be:

remainder = 288 - 208 = 80 fluid ounces

remainder = 80/16 = 5 pints

The teacher will have 5 pints left.

where is the figure

for a it would be 24 children.
