Q:

Jillian has $50 that she plans on investing in an account that will double her money every week. This can be represented by the equation M = 50(2)x where M represents the amount of money she has and x represents the number of weeks that have passed. If she invested it in an account that tripled her money every week, what should be changed in the equation M = 50(2)x to represent the new situation?

Accepted Solution

A:
The part that would change would be the number 2.  It would become a 3 instead of the 2.  Tripling something means to have 3 groups of it.

The reason is that the $50 is not changing, nor would the number of weeks, x be changing.
