The marbles Helena have in all is 4m+3.
Step-by-step explanation:
- Helena puts 'm' marbles in each bag.
- m = Number of marbles in each of the 4 bags.
∴ The marbles in all of the 4 bags = m+m+m+m = 4m
- She had 3 marbles left over.
- Total marbles = Marbles in 4 bags + left over marbles
∴ Helena had a total marble of (4m+3).
