The cost of each daffodils bulb is $0.425

Step-by-step explanation:

The cost of 7 daffodils bulb and 6 tulips bulb = $8.50

The cost of 7 daffodils bulb and 20 tulips bulb = $14.45

Let cost of each daffodils bulb = d

The cost of each tulips bulb = t

According to question

∵ The cost of 7 daffodils bulb and 6 tulips bulb = $8.50

So, 7 d + 6 t = $8.50             .........A

And

∵ The cost of 7 daffodils bulb and 20 tulips bulb = $14.45

So, 7 d + 20 t = $14.45           ..........B

Now, Solving eq A and eq B

(7 d + 20 t) - (7 d + 6 t) = $14.45 - $8.50

Or, (7 d - 7 d) + (20 t - 6 t) = 5.95

Or, 0 + 14 d = 5.95

∴ d =

i.e d = $0.425

So,  cost of each daffodils bulb = d = $0.425

Hence, The cost of each daffodils bulb is $0.425  Answer
