Advanced Math practice question
A shop starts the day with 10 loaves and sells 2 loaves every hour. Which expression gives the number of loaves left after x hours?
- A. 10 − 2xCorrect
- B. 10 + 2x

- D. 10x − 2
Answer: A. 10 − 2x
Start with 10 and take away 2 for each hour.
Why the other answers are wrong
- B. 10 + 2x

- C. 2x − 10
- This is negative for small x.
- D. 10x − 2
- This multiplies the starting stock by the hours.
