To determine the number of marbles originally in each bag, we can set up an equation based on the information given.
Each bag initially has \( m \) marbles, and there are 5 bags. Therefore, the total number of marbles originally in the bags is \( 5m \). After adding 10 marbles to each bag, each bag will have \( m + 10 \) marbles. The total number of marbles will then be:
\[ 5(m + 10) \]
According to the problem, the total number of marbles after adding the 10 marbles to each bag is 80. Thus, we can set up the following equation:
\[ 5(m + 10) = 80 \]
This equation can be solved to determine how many marbles were originally in each bag.
The correct answer corresponds to this equation. If you provide the options A, B, C, and D, I can help identify which one matches this equation.
