Q: 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?
A: 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 is 45.

Q: Heloise has dogs and cats in the ratio of 10:17, with the total number of pets being 189. If she gives 10 dogs to her friend Janet, how many dogs does she remain with altogether?
A:
The total ratio for the number of cats and dogs that Heloise has is 10 + 17 = 27. From the ratios, the fraction representing the number of dogs is 10 / 27, and this represents 10 / 27 * 189 = 70 dogs. If Heloise gives 10 of her dogs to Janet, she remains with 70 - 10 = 60 dogs. The answer is 60.
