Answer:
<u><em>8 stands</em></u>
Step-by-step explanation:
<u><em>Potatoe stands can hold 3 lb</em></u>
<u><em>Tomato stands can hold 6 lb</em></u>
<u><em>So there are 21 pounds of potatoes and 6 pounds of tomatos</em></u>
<u><em>we only need 1 stand for the tomatos (1 stand can hold 6 pounds of tomatoes)</em></u>
<u><em>to find how many stands we need for the potatoes we can divide</em></u>
<u><em>21 / 3 = 7</em></u>
<u><em>so in conclusion we need 7 stands for potatoes and 1 stand for the tomatos</em></u>
<u><em>8 stands in all</em></u>
