A-B Problem A notes:
Suppose x adults and y children visit a theme park one day. The price of an adult ticket is a dollars and the price of a child’s ticket is c dollars. Interpret the following in everyday language using as many vocabulary terms as possible.
1) a = 3c _____________________________

12. A-B Problem A Check:
Suppose x adults and y children visit a theme park one day. The price of an adult ticket is a dollars and the price of a child’s ticket is c dollars. Interpret the following in everyday language using as many vocabulary terms as possible.
a = 3c The cost of an adult ticket (variable a) is three times the cost of a child ticket (variable c).
ax + cy < The product of the price of each adult ticket multiplied by the number of adult tickets sold being added to the product of the price of each child ticket multiplied by the number of child tickets sold is less than one thousand dollars.

A-B Problem B SOLVE!!
Shannon is trying to determine the cost of producing her gourmet popcorn. Running the factory for one day represents $600 in salary and building costs. Each pound of popcorn costs an additional 30 cents in supplies. She writes down the following equation: C = x
Explain how she developed this equation by identifying what each variable and term represents.

14. A-B Problem B Check!!
Shannon is trying to determine the cost of producing her gourmet popcorn. Running the factory for one day represents $600 in salary and building costs. Each pound of popcorn costs an additional 30 cents in supplies. She writes down the following equation: C = x
Explain how she developed this equation by identifying what each variable and term represents.
She created this equation by identifying the daily constant of $600 in salary and building costs. She also identified the coefficient of 0.30 for the cost of supplies for each (variable X) pound of popcorn made at the factory.

16. Find the total cost. Problem A MOVIES
Evaluate an expression in two variables
The total cost of seeing a movie at a theater can be represented by the expression a + r where a is the cost (in dollars) of admission and r is the cost (in dollars) of refreshments. Suppose you pay $7.50 for admission and $7.25 for refreshments.
Find the total cost.

17. and $7.25 for refreshments. Find the total cost. MOVIES
Problem A
Evaluate an expression in two variables
The total cost of seeing a movie at a theater can be represented by the expression a + r where a is the cost
(in dollars) of admission and r is the cost (in dollars) of refreshments. Suppose you pay $7.50 for admission
and $7.25 for refreshments. Find the total cost.
MOVIES
SOLUTION
Total cost r a + =
Write expression.
7.25
7.50 + =
Substitute 7.50 for a and 7.25 for r.
14.75 =
Add.
ANSWER
The total cost is $14.75.

18. Problem B
Suppose you go back to the theater with a friend to see an afternoon movie. You pay for both admissions. Your total cost (in dollars) can be represented by the expression 2a. If each admission costs $4.75, what is your total cost?

19. Problem B
Suppose you go back to the theater with a friend to see an afternoon movie. You pay for both admissions. Your total cost (in dollars) can be represented by the expression 2a. If each admission costs $4.75, what is your total cost?
a = 4.75
2a = 2(4.75)
2a = 9.50
$9.50
