Final answer:
Andy pours a total of 2 pints of coffee, after converting 32 fluid ounces (the total amount from four 8 ounce cups) using the equivalence of 16 ounces per pint.
Step-by-step explanation:
To convert the total amount of coffee Andy pours into pints, we first need to understand the relationship between fluid ounces, cups, and pints. According to the unit equivalence, 1 cup is equal to 8 fluid ounces, and 1 pint is equal to 2 cups or 16 ounces. Andy pours four 8 fluid ounce cups of coffee, which totals 32 fluid ounces.
Now, to find out how many pints this is, we divide 32 fluid ounces by the number of ounces in a pint.
32 fluid ounces ÷ 16 ounces per pint = 2 pints
Therefore, Andy pours a total of 2 pints of coffee for the guests.
