Question

5 liam has a bag of beads. he gets 20 beads from his sister. liam wrote the expression $b + 20$ to represent the total number of beads he has now. what does $b$ represent in this situation? a the number of beads his sister gave him b the total number of beads he has now c the number of beads he had before getting more from his sister d the number of beads he gave away

Explanation:

The expression $b + 20$ represents Liam's current total beads. The 20 is the beads his sister gave him, so $b$ must be the amount he had before receiving the new beads. Option A is the 20, B is the total $b+20$, and D is irrelevant as no beads were given away.

Answer:

C. The number of beads he had before getting more from his sister
