This Week's Problem: "Spinach Rows"
Q: Pea, tomato, and spinach plants are planted in a field. For every 2 pea plants, there are 3 tomato plants, and for every 5 pea plants, there are 6 spinach plants. Spinach is sown 18 plants to a row and tomatoes 12 plants to a row, with no partial or mixed-crop rows. What is the minimum number of spinach plants in the field?
I took a stab at this one, but am still unsure of my answer. Work the problem out for yourself, then look at my answer in the comments to this post to see whether we reasoned it out the same way. I think I may have gotten this wrong, but I'm not sure.
