3. A gardener plants two types of flowers. The first type yields 5 flowers for every 2 plants, while the second type yields 15 flowers for every 6 plants. Write the equation that represents the relationship between the number of plants and flowers for each type.

• flowers1 = (5/2) * plants1, flowers2 = (5/2) * plants2

• flowers1 = (5/3) * plants1, flowers2 = (15/4) * plants2

• flowers1 = (10/4) * plants1, flowers2 = (3/5) * plants2

• flowers1 = (2/5) * plants1, flowers2 = (6/15) * plants2
