Geli is committed to her 3 times a week workout. On her first day, she started doing 10 push-ups. Her fitness trainer encouraged her to add 5 more push-ups each day. How many push-ups will she do in total throughout her first week? Let's answer step by step:
On the first day, she will do 10 push - ups. On the second day, she will do 10 + 5 = 15 push - ups. On the third day, she will do 15 + 5 = 20 push - ups. So, Geli will do a total of 10 + 15 + 20 = 45 push - ups in a week. The answer: 45.
