Answer:
$1.25
Explanation:
To do this problem, you need to note that they bought two of almost everything. You are also working backwards at first to get how much they spent total and then taking away the expenses.
The first step is finding how much money they spent total, and you can do this by adding the gift certificate to the price:
44.5 + 10 = $55.50
Now, you see that they each bought a ticket for $20 EACH. There were two tickets (one for Andy, one for Nick). So multiply 20 by 2 and subtract that from your total cost.
$55.50 - (2 * $20) =
$55.50 - $40 =
$15.5
They bought a total of TWO sandwiches at 6.50 each. So repeat these steps, subtracting from the number above (underlined)
$15.50 - ($6.50 * 2) =
$15.50 - $13 =
$2.5
They bought two drinks that totaled to be $2.50.
To find the cost of ONE drink, divide this number by 2:
$2.50/2 =
$1.25
