In this problem, we want to write an expression for the total cost of buying the items for all the players.
The items of each player are:
• a t-shirt that costs $12,
,
• stocks that cost $4,
,
• a hat that costs $x.
The cost of all the items for one player is just the sum of the prices:

Now, the cost for all the team is the last expression times the number of players:

To simplify the last expression, we apply the distributive property for the multiplication:
