###Human: Ian is looking to lose some weight.  He decides to start jogging around his apartment complex every night to burn some calories.  He does 5 laps around the complex every night.  Each lap is 100 feet.  If it takes 25 feet of jogging to burn a calorie, how many calories does Ian burn after 5 days of jogging like this?, ### Assistant: First, we need to determine how many feet Ian runs in a week. We begin this by multiplying the number of laps by the number of feet per lap, performing 5*100= 500 feet per day.
Since there are 5 days in the period being measured, this means Ian runs 500*5= 2500 feet jogged.
Since it takes 25 feet of jogging to burn a calorie, this means Ian burns 2500/25=100 calories burned jogging throughout the week. 
 So the answer is :  100
