2,300 (calories consumed) - ________ (2 hours sitting in class) - ______ (1 hour making beds) = ____________ (calories left)

○ 1925 calories remaining
○ 1950 calories remaining
○ 1975 calories remaining
○ 2000 calories remained

Explanation:

Step1: Calculate calories used for sitting in class

Since sitting in class burns 100 calories per hour, for 2 hours, the calories used are $100\times2 = 200$ calories.

Step2: Calculate calories used for making beds

Making beds burns 175 calories per hour, so for 1 hour, 175 calories are used.

Step3: Calculate remaining calories

The initial calories consumed are 2300. Subtract the calories used for sitting in class and making beds. So, $2300-200 - 175=1925$ calories.

Answer:

1925 Calories Remaining
