Algebra practice question

A jar holds $12, and $3 is added to it every week. Which function gives the amount A, in dollars, in the jar after w weeks?

  1. A. A = 12 + 3wCorrect
  2. B. A = 3 + 12w
  3. C. A = 15w
  4. D. A = 12 − 3w

Answer: A. A = 12 + 3w

Start at 12 and add 3 for each week.

Why the other answers are wrong

B. A = 3 + 12w
This starts at 3 and adds 12 a week.
C. A = 15w
This has no starting amount.
D. A = 12 − 3w
This takes money out.
