Question

You are in charge of advertising for the drama club's next performance. You can make two signs from a poster board that is 36 inches long and 24 inches wide. Each poster board costs $0.75. Question: Write and equation that shows the relationship between the number of signs and the total cost of the poster board. Let n represent the number of signs and C represent the total cost of the poster board.

Answer 1

C = 0.75(n/2)

Explanation:

For each pair of signs, $0.75 is needed for the posterboard.

C = 0.75(n/2)

This can be simplified to ...

C = 0.375n . . . . for n an even number

__

If posterboard only comes in the size given, then the more technically correct answer is ...

C = 0.75·ceiling(n/2)
