Advanced Math practice question
A box holds 2y pencils. Which expression gives the number of pencils in 3 such boxes?
- A. 6yCorrect
- B. 5y
- C. 2y + 3
- D. 3y + 2
Answer: A. 6y
3 boxes of 2y is 3(2y) = 6y.
Why the other answers are wrong
- B. 5y
- 5y adds 3 to the coefficient instead of multiplying.
- C. 2y + 3
- Adding 3 pencils is not the same as 3 boxes.
- D. 3y + 2
- This reverses the roles of 2 and 3 and adds.
