Cheryl purchased 5 identical hollow pine doors, and 6 identical hollow oak doors.

Let the cost of pine door be x.
Since the price of the oak door is twice the price of the pine door, the cost is 2x.
Since she gets a discount of 25% on the oak door,
she would have to pay 75% of the cost, which is $$\frac{3}{4}*2x = 1.5x$$

Since the cost of pine door is 40$, the cost of the oak door is 60$

Therefore, the total cost of the 11 doors is $$5*40 + 6*60 = 200 + 360 = 560$$(Option C)

Given price of pine door $$= 40$$

Number of pine doors $$= 5$$

Total price of pine doors purchased $$= 5 * 40 = 200$$

Price of oak door = twice the price of pine door $$= 2 * 40 = 80$$

Cheryl was given 25% discount on oak doors = 75% of 80 $$= \frac{75}{100} * 80 = 60$$

Number of oak doors $$= 6$$

Total price of oak doors purchased $$= 60* 6 = 360$$

Total price of all 11 doors $$= 200 + 360 = 560$$. Answer (C) ...

Pine Doors = $x =$40
Oak Doors = $2x =$80
25% discount given on regular price of oak doors.
=> Oak Doors = $1.75x =$60

Total Price = 5*40 + 60*6 = 560

Since the regular price of each hollow pine door = 40 dollars, the regular price of each solid oak door is (2)(40) = 80 dollars.

With a 25% discount, each solid oak door is sold for 0.75(80) = 60 dollars.

So, the six oak doors cost 6 x 60 = 360 dollars, and the five pine doors cost 5 x 40 = 200 dollars. Thus, the total is 560 dollars.

There's no significance as you've correctly identified that 11 doors were sold acc to the first sentence
