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? How many feet does Ian run in a day? ** 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= <<5*100=500>>500 feet per day. How many feet does Ian run in a week? ** Since there are 5 days in the period being measured, this means Ian runs 500*5= <<2500=2500>>2500 feet jogged. How many calories does Ian burn jogging? ** Since it takes 25 feet of jogging to burn a calorie, this means Ian burns 2500/25=<<2500/25=100>>100 calories burned jogging throughout the week. #### 100 Andy started out the year weighing 156 pounds. He then grew 3 inches and gained 36 pounds. Andy wasn't happy with his weight and decided to exercise. Over the next 3 months, he lost an eighth of his weight every month.
