Ms. Brackemyer is collecting pencils.  The function p(x)=5x+12 tells us the total amount of pencils Ms. Brackemyer has after collecting for x number of days.  What is the meaning of p(8)=52?

• Ms. Brackemyer starts with 8 pencils and ends with 52.
• After 8 days, Ms. Brackemyer has 52 pencils.
• Ms. Brackemyer starts with 52 pencils and gets 4 more every day.
• Every day, Ms. Brackemyer gets 4 new pencils until she has 52.

Flagship Cinemas sells movie tickets that are $4 for matinees(x) and $7 for regular(y). One night, the theater sells 578 tickets and collects $3365 in total ticket sales.

Which system best represents the situation?

• 4x + 7y = 578

  x + y = 3365

• 4x + 7y = 3365

  x + y = 578

• 4y + 7x = 578

  x + y = 3365

• 4y + 7x = 3365

  x + y = 578
