Hi AbeNeedsAnswers,

We're told that Cheryl purchased 5 identical hollow pine doors and 6 identical solid oak doors. The REGULAR price of each solid oak door was TWICE the REGULAR price of each hollow pine door, but Cheryl was given a discount of 25% off the regular price of each solid oak door. The regular price of each hollow pine door was $40. We're asked for the total price of all 11 doors.

As wordy as this prompt is, solving it really comes down to just organizing the given information and doing a bit of arithmetic...

To answer this question, we need to determine the price of the two types of doors:
Regular price of hollow pine door = $40
Regular price of solid oak door = (2)($40) = $80
Discount price of solid oak door = $80 - (.25)($80) = $60

Now that we have the prices, we can figure out the total:
5($40) + 6($60) = $200 + $360 = $560

Final Answer: C
