markell spends 2 hours lifting weights, 3 hours sitting in class, and eating for 1 hour. if he consumes 3100 calories, how many calories remain to be used?
o 1675 calories
o 1680 calories
o 1690 calories
o 1700 calories

Explanation:

Step1: Calculate calories used for lifting weights

Calories used for lifting weights = 2×500 = 1000 (since 500 calories per hour and 2 hours)

Step2: Calculate calories used for sitting in class

Calories used for sitting in class = 3×100 = 300 (100 calories per hour and 3 hours)

Step3: Calculate calories used for eating

Calories used for eating = 1×125 = 125 (125 calories per hour and 1 hour)

Step4: Calculate total calories used

Total calories used = 1000 + 300+125 = 1425

Step5: Calculate remaining calories

Remaining calories = 3100 - 1425 = 1675

Answer:

1675 calories
