Israel planted 4 tomato seeds in his garden. Then he planted flower seeds in each of his three neighbor's gardens. Which expression represents the number of seeds Israel planted?

A. 4s + 3
B. 4 + 3s
C. 4 – 3s
D. 3s – 4

B. 4 + 3s

The expression that represents the number of seeds Israel planted is:

A. 4s + 3

To determine the expression that represents the number of seeds Israel planted, we need to consider the initial number of tomato seeds he planted and the number of flower seeds he planted in each of his neighbor's gardens.

Israel planted 4 tomato seeds in his garden, represented by the number 4. He then planted flower seeds in each of his three neighbor's gardens, represented by the expression 3s, where 's' represents the number of flower seeds planted in each garden.

To find the total number of seeds Israel planted, we need to add the number of tomato seeds (4) to the number of flower seeds (3s). Therefore, the expression that represents the number of seeds Israel planted is:

4 + 3s

Hence, the correct answer is option B: 4 + 3s.
