Apitcher contains 40 fluid ounces of iced tea. shelby pours 3 cups of iced tea. how many pints of iced tea are left?

Given;
40 fluid ounces of iced tea.

We know,
1 cup = 8 fluid ounce
1 pint = 2 cup

Now,
8 fluid ounce = 1 cup
1 fluid ounce = 1 / 8 cup
40 fluid ounce = (1 / 8) * 40 cup
So, 40 fluid ounce = 5 cup

Now,
We, used 3 cups of iced tea. So, we only have 2 cups of iced tea left.

We have,
2 cups = 1 pint

So, 1 pint of iced tea is left!

8 ounce=1 cup
so 3 cups=8 times 3 ounces=24 ounces
40-24=16 counces left

8 ounces=1 cup 
16 ounces=2 times 8
16=2 cups
2 cups=1 pint
1 pint left
