The correct answer is (False)
Since they buy 2 $6.50 tickets, they already spend $13 without buying any popcorn or drinks.
For the expression, you can write-
$5.50d + $6.00p + $13 // d representing however many drinks they buy and p representing the amount of popcorn they buy.
This expression will give you the total amount of money spent with varying amounts of drinks and popcorn bought.
so 3-8x3 to the power of 2 would be this....
3-8x3x3= -45
