Explanation:

Step1: Calculate calories used for each activity

Biking for 1 hour: 900 calories (from table). Studying for 2 hours: $2\times105 = 210$ calories. Fast - walking for 1 hour: 300 calories.

Step2: Calculate total calories used

Total calories used = $900+210 + 300=1410$ calories.

Step3: Calculate remaining calories

Calories consumed is 3100. Remaining calories = $3100 - 1410=1690$ calories.

Answer:

1690 calories
