Can you please explain number 9 on page 49 in the translating between words and math section? Thank you
Sure. Here’s the question for everyone else following along:
![](https://i0.wp.com/pwntestprep.com/wp-content/uploads/2020/06/image.png?resize=372%2C300&ssl=1)
We know that when m = 0, the number of accounts was 4,523.
We also know that 5 years later, there were exactly 41,783 accounts. There are 12 months in a year, so that means m = 60 (). We can use that to plug in 41,783 for
, 60 for m, and solve for k.
Does that help?
