A student has 5 bags of marbles. each bag originally contains m marbles after adding 10 marbles to each bag, there are a total of 80 marbles. which equation can be solved to determine how many marbles were oringinaly in each bag

Answer 1

Let's denote the number of marbles originally in each bag as \( m \). Initially, since there are 5 bags, the total number of marbles is:

\[ 5m \]

After adding 10 marbles to each bag, the number of marbles in each bag becomes \( m + 10 \). Therefore, the total number of marbles in all bags after the addition is:

\[ 5(m + 10) \]

According to the problem, this total equals 80:

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

To summarize, the equation you can solve to determine how many marbles were originally in each bag is:

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