Define the Variable

Read each design plan. Identify what the variable represents and connect it to an expression.

1.
The 3D-printing club has 180 grams of filament on a spool. After printing a part, the amount left can be modeled by 180 − n. What does n represent?
  • A. The grams of filament used to print the part.
  • B. The number of parts printed from the spool.
  • C. The grams of filament on the spool before printing.
  • D. The grams of filament left on the spool.
2.
A display stand needs 4 identical feet. Each foot uses an unknown amount of filament. Which definition of n lets 4n represent the total grams of filament for the feet?
  • A. Let n be the grams of filament used for all four feet.
  • B. Let n be the grams of filament used for one foot.
  • C. Let n be the number of feet on the display stand.
  • D. Let n be the number of stands the club will print.
3.
The club can choose a model height of 6, 8, 10, or 12 centimeters. Let n represent the chosen height in centimeters. Select every value n can represent in this plan.
