Question

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?

Answer 1

The cost of each daffodils bulb is $0.425

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 =
`(5.95)/(14)`

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
