Question 908894
This is written in a confusing manner.  Have you already bought that shirt?  It would appear that you have not.  So far, then, you have spent only $5 on clothes.  Now you're going to spend $15 on that shirt and $5 on socks.  Your total expenditure at that point will be the $5 you already spent and the $20 you're spending this month, for a grand total of $25.
