Final answer:
Anna served 5 cups of soup in total, leaving 7 cups of soup in the pot after serving 4 bowls of 10 fluid ounces each. We calculate the amount served by converting fluid ounces to cups and then subtracting from the total.
Step-by-step explanation:
The student has asked how many cups of soup are left in the pot after Anna fills 4 bowls with 10 fluid ounces of soup each. Since 1 cup is equal to 8 fluid ounces, we start by converting the 10 fluid ounces in each bowl to cups. We do this by dividing the number of fluid ounces by 8, which represents the unit equivalence.
10 fl oz ÷ 8 fl oz/cup = 1.25 cups
Now, multiply this amount by the number of bowls to find the total amount of cups served:
1.25 cups/bowl × 4 bowls = 5 cups
Anna originally had 12 cups of soup. To find out how many cups are left after serving, subtract the amount served from the total amount:
12 cups - 5 cups = 7 cups of soup left in the pot.
