Here, the question is incomplete.

Helena lost her marbles. But then she found them and put them in 4 bags with m marbles in each bag. She had 3 marbles left over that didn't fit in the bags. How many marbles does Helena have in all? Write your answer as an expression.

The total number of bags filled with marbles  = 4

The number of marbles in each bag = m

So, total number of marbles  in 4 bags  = 4 x ( Marbles in 1 bag)  

                                                                  = 4 x (m)  = 4 m

The left  number of marbles  = 3

So, the total marbles  = (total marbles in 4 bag)  +  left out marbles

or, T  = 4  m + 3

Hence, the expression for total marbles is given as: T = 4 m + 3
