Final answer:
To find the calories of a pumpkin pie, you need to know the serving size and the number of calories in one serving. According to the information provided, one serving is 1/8th of the pie. With this information, you can calculate the calories in 1/8th of the pie by converting the serving size to cups and multiplying it by the calories per cup.
Step-by-step explanation:
To find the calories of a pumpkin pie, you need to know the serving size and the number of calories in one serving. According to the information provided, one serving is 1/8th of the pie. The label also states that there are 250 calories per serving of a cup of food. Since the serving size of the pie is 1/8th, you need to calculate how many cups are in 1/8th of a cup and then multiply it by the calories per cup to find the calories in 1/8th of the pie.
First, convert 1/8th of a cup to cups. Since there are 8 tablespoons in a cup, and 1/8th of a cup is 1 tablespoon, it is equal to 1/8th of a cup or 0.125 cups.
Then, multiply 0.125 cups by 250 calories per cup (from the label) to find the calories in 1/8th of the pie.
0.125 cups * 250 calories/cup = 31.25 calories.
