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)

If the regular price of each hollow pine door was $40, what was the total price of all 11 doors?
A. $320 B. $540 C. $560 D. $620 E. $680 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. Answer: C

We are already given that she bought total 11 doors in first sentence. There's no significance as you've correctly identified that 11 doors were sold acc to the first sentence Posted from my mobile device

A. $320 B. $540 C. $560 D. $620 E. $680 Not a lot to say about this question; 5 pine doors, each of which costing $X; 6 oak doors, each of which costing twice, so $2X; but there's a discount, that's one. Two, this is actually $40, so 2X is going to be $80. Obviously, if we subtract 25% we need to know these common percents by heart, that's 1/4, so if we subtract 1/4 of 80, we're left with 60, so $60 times 6 doors, $40 times 5 and doors, that is a 200 plus a 360, the total cost is going to be 560, and the correct answer is C.
