Question

Larry has three times as many pencils as Ben. Dejuan has four less than the number of pencils as Ben. Write the expression that would be the total number of pencils for all three of them.

Answer 1

The total number of pencils for Larry, Ben and Dejuan is expressed as:

5B - 4

Explanation:

Let B represent the number of pens Ben has.

》Ben = B

》Larry = 3 × B = 3B

》Dejuan = B - 4

∴ Total number of pencils for the three of them

= B + 3B + (B - 4)

= 5B - 4
