1) 29
2) 30
3) 31
4) 32

Answer 1

By adding the large and small marbles together, we determine that there are 29 marbles in total, making option 1) the correct answer.

Step-by-step explanation:

To find the total number of marbles in the box, we simply add the number of large marbles to the number of small marbles. There are 19 large marbles and 10 small marbles. So, the total is:

19 (large marbles) + 10 (small marbles) = 29 marbles in total.

Therefore, the answer to the question 'How many marbles are there in total?' is 29 marbles, which corresponds to option 1).
