Question
Bill eats 3 slices of cornbread for breakfast that contains a total of 123 calories. Bob eats 4 slices of pizza that contains 148 calories. The unit rate of higher calorie food per slice is ___________.
- 64
- 41
- 37
- 50
Hint:
Unit rate of food refers to the amount of calories contained in 1 slice of that particular food item.
Unit rate = Total Calories/ Number of slices.
Unit rate of higher calorie food per slice will be determined by calculating Unit rate of calorie offered by 2 food items and selecting the one with highest rate per slice.
The correct answer is: 41
Given-
For Corn bread- A. Total Calories = 123 and Number of slices = 3
For Pizza- A. Total Calories = 148 and Number of slices = 4
To find- Unit rate of higher calorie food per slice
Solution-
Unit Rate for Cornbread = Total Calories / Number of slices
∴ Unit Rate for Cornbread = 123 / 3 ....................... (As per given information)
∴ Unit Rate for Cornbread = 41 calories per slice.
Unit Rate for Pizza = Total Calories/ Number of slices
∴ Unit Rate for Pizza = 148 / 4 ....................... (As per given information)
∴ Unit Rate for Pizza = 37 calories per slice.
From the above calculations, we observe that Unit rate of calorie count per slice of Cornbread is higher (i.e. 41 calories per slice) among the 2 food items.
Hence, Unit rate of higher calorie food per slice among the 2 food items is Cornbread i.e. 41 calories per slice.
Final Answer- 'Option B' i.e. 41.
