Problem of the Week
Problem B
Fields of Flowers

Sadie has garden beds that are \(11\) m by \(14\) m. She wants to grow giant sunflowers in one of her garden beds and dwarf sunflowers in another garden bed.

1. Sadie spaces the giant sunflower seeds \(50\) cm apart, in rows that are \(50\) cm apart, leaving a \(100\) cm border on all sides of the garden bed. How many giant sunflower seeds can she plant in one garden bed?

2. In another garden bed, Sadie plants dwarf sunflower seeds. She spaces the seeds \(25\) cm apart, in rows that are \(25\) cm apart, leaving a \(100\) cm border on all sides of the garden bed. How many dwarf sunflowers can she plant in this garden bed?

3. All of Sadie’s sunflowers have germinated and matured, but then in a cold early frost one evening, she loses \(20\%\) of the giant sunflowers and \(10\%\) of the dwarf sunflowers. If Sadie sells all the surviving sunflowers at \(\$5.00\) each for the giants and \(\$3.00\) each for the dwarfs, which crop will provide the greater income?
