To set up the equation based on the information provided:

1. Each bag originally contains \( m \) marbles.
2. There are 5 bags, so the total number of marbles originally is \( 5m \).
3. After adding 10 marbles to each bag, each bag now contains \( m + 10 \) marbles.
4. The total number of marbles after adding the 10 marbles to each bag becomes \( 5(m + 10) \).

According to the problem, this total equals 80:

\[
5(m + 10) = 80
\]

This is the equation that can be solved to determine how many marbles were originally in each bag.

Now you can see which option matches this equation in your list (A, B, C, D). If you need guidance on identifying the correct option or if you have the options available, please share them!
