Question

A box contains 19 large marbles and 10 small marbles. Each marble is either green or white. How many marbles are there in total?

1) 29
2) 30
3) 39
4) 40

Answer 1

The total number of marbles in the box is the sum of large and small marbles, which adds up to 29 marbles in total.

Step-by-step explanation:

To determine the total number of marbles in the box, we simply need to add the number of large marbles to the number of small marbles. That is:

Total marbles = Number of large marbles + Number of small marbles

Total marbles = 19 large marbles + 10 small marbles

Total marbles = 29 marbles

Therefore, the answer to how many marbles are there in total is 29, which corresponds to option 1).
