Final answer:
To find the total number of green marbles (g) that Matthew and Sarah have, use the equation g = (3 × 25) + (5 × 48).
Step-by-step explanation:
The student’s question involves determining the total number of green marbles that Matthew and Sarah have combined. Matthew has 3 bags with 25 green marbles in each, and Sarah has 5 bags with 48 green marbles in each.
To find g, the total number of green marbles, we can set up the following equation:
g = (Number of Matthew's bags × Marbles per Matthew's bag) + (Number of Sarah's bags × Marbles per Sarah's bag)
Plugging in the numbers we have:
g = (3 × 25) + (5 × 48)
This equation will calculate the total number of green marbles that Matthew and Sarah have together.
