Mario and luigi are comparing their daily caloric intake. each day luigi chooses 100-calorie snacks such as carrots while mario chooses to snack on chips and candy that have 200 calories each.

Question

Luigi: (1,100), (2,200), (3,300)
Mario: (1,200), (2, 400), (3,600)

What is Mario's rate of change? and what is Luigi's rate of change?

Answer 1

To calculate the rate of change, we can find the difference in daily caloric intake between consecutive days for each person.

For Luigi:
Rate of change = (200 - 100) + (300 - 200) = 100 + 100 = 200 calories

For Mario:
Rate of change = (400 - 200) + (600 - 400) = 200 + 200 = 400 calories

Therefore, Luigi's rate of change is 200 calories and Mario's rate of change is 400 calories.
