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?
Since one out of every 3 rows will contain tomato plants, there will be 15 / 3 = 
<gadget id="calculator">15/3</gadget>
<output>5</output>
5 rows of tomato plants.
This gives her enough room to plant 5 rows * 8 plants/row = 
<gadget id="calculator">5*8</gadget>
<output>40</output>
40 tomato plants.
The plants will produce a total of 40 * 3 = 
<gadget id="calculator">40*3</gadget>
