She bought 7 daffodils and 6 tulips on friday and paid $8.50. she bought more bulbs on saturday, 20 tulips and 7 daffodils and cost $14.45.how much does a daffodil bulb cost?

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

step-by-step explanation:

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
