[Question]: On Black Friday a popular electronics store sells 327 televisions. This is 50 more than they sold last Black Friday. If this sales trend continues and they sell 50 more televisions each year for three years, how many televisions will they sell on Black Friday three years from now?
[Answer]: The electronics store sold 327 televisions this Black Friday and might sell 50 more televisions the next year, for a total of 327 + 50 = 377 televisions. The second year they might sell 377 + 50 = 427 televisions. The third year, if they continue to sell 50 more televisions than they did the previous year, they will sell 427 + 50 televisions = 477 televisions on the Black Friday three years from now.
So the answer is 477.

[Question]: A pen and pencil have a total cost of $6. If the pen costs twice as much as the pencil, what is the cost of the pen?
[Answer]: Let x be the cost of the pencil. If the pen costs 2 times the cost of the pencil, then it costs 2x. Adding the cost of the pen and pencil we get 2x + x = 3x. Since the total cost is $6 then 3x = $6 therefore x = $6 / 3 = $2. One pen is equal to 2 * x which is 2 * $2 = $4.
So the answer is 4.

[Question]: A soccer team had 24 players prepared for a soccer game. The first half saw 11 players start the game with 2 substitutions made. In the second half, the team made twice as many substitutions as it made in the first half. How many players on the team did not play that day?
[Answer]:
With two substitutions, 11 + 2 = 13 players from the team played the game in the first half. In the second half, the team made twice the number of substitutions it made in the first half, a total of 2 * 2 = 4 substitutions. The total number of players who played the game is 13 + 4 = 17. If the soccer team had 24 players prepared for the soccer game, the number of players who did not play the game is 24 - 17 = 7 players.
So the answer is 7.
