Answer:

Step-by-step explanation:

The ratio is 4 daffodils to 3 tulips.

Let the daffodils = d

Let the Tulips = t

d/t = 4/3                    Cross Multiply

3d = 4t                      Divide by 3

3d/3 = 4t/3                Combine

d = 4/3 * t

d + t = 28

4/3 t + t = 28             Change 1t to 3/3 t

4/3 t + 3/3t = 28       Add the fractions.

7/3 t = 28                 Multiply both sides by 3/7

3/7 * 7/3t = 28 * 3/7

t = 4 * 3

t = 12

12 tulips were planted. This is the algebraic method of doing the question. If you are in an algebra class, the question really should be done this way.
