Answer:
The cost for a soft drink was $3.50
Explanation:
Angela has a $15 gift certificate.
Total cost for the popcorn and drink and movie tickets = $15 + $23.50 = $38.50
The cost of 2 movie tickets = $13 x 2 = $26
The cost of 2 popcorn = $4.50 x 2 = $9.00
Now we have to find the cost for a soft drink.
Let "x" be the cost for a soft drink.
Total cost = x + The cost of 2 popcorn + The cost of 2 tickets
$38.50 = x + $9 + $26
$38.50 = x + $35
x = $38.50 - $35
x = $3.50
So the cost for a soft drink was $3.50
