Practice Creates Learning Alyiah and her family buy snacks at the movies. They buy 3 pretzels and 4 drinks for \( \$ 17.50 \). The cost of a pretzel is the same as the cost of a drink. The situation can be represented by the graph and the system of equations shown, where \( p \) is the cost of a pretzel and \( d \) is the cost of a drink. 3 pretzels and 4 drinks cost \( \$ 17.50 .3 p+4 d=17.50 \) A pretzel costs the same as a drink \( p=d \) What is the cost of each pretzel? What is the cost of each drink?

Ginger was running the concession stand at the DinoPlex Movie Theater. At the DinoPlex concession stand, pretzels are $3 each, hamburgers are $6 each, water is $2.50 per bottle, and potato chips are $3.50 per bag. During her shift at the DinoPlex, Ginger sold a combined total of 154 pretzels, hamburgers, bottles of water, and bags of chips, for a total of $557.50 (not including tax). The number of bags of chips she sold was five less than twice the number of pretzels, and the number of pretzels was three more than four times the number of water bottles. Set up an appropriate system of linear equations. How many of each item were sold? The combined total is 154. I need to know how many pretzels were sold, how many hamburgers were sold, bottles of water sold, and bags of chips sold.

Jacob and Zachary go to the movie theater and purchase refreshments for their friends. Jacob spends a total of $18.25 on two bags of popcorn and three drinks. Zachary spends a total of $27.50 for four bags of popcorn and two drinks. Part A) Write a system of equations that can be used to find the price of one bag of popcorn and the price of one drink. Part B) Using these equations, determine and state the price of a bag of popcorn and the price of a drink, to the nearest cent.

Judy took $30 with her to spend on popcorn and drinks for herself and her friends at the movie theater. The price for each bag of popcorn was $5. The price of each drink was half the price of a bag of popcorn. Sketch the graph that represents the situation and label the intercepts. Use one axis to represent the number of bags of popcorn and the other axis to represent the number of drinks. Explain your graph.
