With your statement that "There are no additional details about my question. It is straight forward in the question." Assumignsay that Dots is selling in April, I get, letting x be the number of T-shirts sold

 

2x + 4 (317 -x) = 646, so that x = 311, the number of T-shirts.  Number of shorts = 6.

Answer 2

Let x = the number of T shits

Let y = the number of shorts

 

first sentence says you sold a total of 317 of both.....so x + y= 317.

So now the total sales. If you sold 7 shirts at $2 each, you would have $14. Taking a concrete example to make sure you're setting up the problem correctly is very beneficial. We got 14 by the price, 2, times the number of items 7. So our second equation is

2x + 4y = 646.

 

Can you solve this system of equations?

x + y= 317 

2x + 4y = 646
