<human>:  Aubrey is planting tomatoes and cucumbers in her garden. For each row of tomato plants, she is planting 2 rows of cucumbers. She has enough room for 15 rows of plants in total. There is enough space for 8 tomato plants in each row. If each plant produces 3 tomatoes, how many tomatoes will she have in total?
<bot>: How many rows of tomato plants are there? ** Since one out of every 3 rows will contain tomato plants, there will be 15 / 3 = <<15/3=5>>5 rows of tomato plants.
How many tomato plants are there? ** This gives her enough room to plant 5 rows * 8 plants/row = <<5*8=40>>40 tomato plants.
How many tomatoes will the plants produce? ** The plants will produce a total of 40 * 3 = <<40*3=120>>120 tomatoes.
