Answer:
S= $165 + $15*W
Step-by-step explanation:
The total amount Mario has saved at the end of any W week is called S.
$ 165 is the amount that Mario has already saved.And you know that at the end of each week he saves $ 15. So, for example, in week one Mario will have saved $ 15, in week two $ 30, in week three $ 45 and so on. This is expressed by the relationship $ 15*W. Taking into account that this amount saved is in addition to the $ 165 that Mario had already saved, the total amount that he has saved at the end of any week is:
S= $165 + $15*W
