Question 272192: Greetings,
I was wondering you could please assist me with how to solve the following problem:
Bob just bought a new pedometer & wants to attempt walking a total of 130,000 steps in a 10-day period. Once he starts using it, he realizes that he is out of shape & will need to acclimate slowly to achieve this goal. He decides to start at 4000 steps on the first day & increase by a fixed number of steps each day, over the next 9 days. What is the number of steps that he must increase by each day, in order to achieve the goal of 130,000 total steps in a 10-day period?
I thank you in advance for your assistance!
