Angela and Neil are going to the movies. They each bought a medium popcorn, and Neil got a small soft drink. Angela had a $5 gift certificate to put toward the cost, and Neil paid the rest, which came to $27.90. A movie ticket costs $10.00, and a medium popcorn costs $5.50. How much does a soft drink cost at the theater? slove
well, you have 27.90. you add the $5 from the gift certificate to get 32.90. subtract $20 (2 movie tickets) to get 12.90. subtract $11 (2 popcorns) to get 1.90, which is the cost of the soft drink.
