Answer 1

@rishavraj can you help?

Answer 2

@Mehek14 @welshfella Can you help?

Answer 3

The second part is definitely $62.50 per month. Since the the problem gives you the amount in four months just divide by 4 to get a one month period.

Answer 4

oh okay, thanks! @luffingsails Cause I was confused wheater it's that one or the first one

Answer 5

The difference is that they are talking unit measure. Which usually has a magnitude of 1... in the case of the $125 every *2* months... you can see that it isn't a unit measure. A unit measure would be 1 month.

Answer 6

Yeah, I understand now, thanks! Do you know the first question? (:

Answer 7

I'm looking at it. Trying to figure out how to do it.
