Final answer:
To determine the calorie content in one cup when there are 75 calories in 3/4 cup, we calculate the proportion (75 calories / 0.75 cups) to find that one cup contains 100 calories.
Step-by-step explanation:
To find out how many calories are in one cup when there are 75 calories in 3/4 cup, we can set up a simple proportion. Since the number of calories directly varies with the volume, if 3/4 cup has 75 calories, then 1 full cup would have a ratio of 75 calories : 0.75 cups = x calories : 1 cup. Solving for x gives us:
x = (75 calories)/(0.75 cups) * 1 cup = 100 calories.
Therefore, there are 100 calories in 1 cup of this particular food item.
