Algebra practice question
Ana paid $37.50 for 5 identical notebooks and a pen that cost $7.50. What was the price, in dollars, of each notebook?
Answer: 6
5n + 7.50 = 37.50 → 5n = 30 → n = 6.
Common wrong answers
- If you answered 9
- 9 comes from (37.50 + 7.50) ÷ 5, adding the pen's price instead of subtracting.
- If you answered 30
- 30 is the cost of the five notebooks together.
- If you answered 7.5
- 7.50 is 37.50 ÷ 5, ignoring the pen.
