Q. Ed is booking a hotel room for his vacation. If he stays for 77 nights, the hotel will give him a $280\$280 discount. He notices that the amount he would pay for 77 nights with the discount is the same as the amount he would pay for 55 nights without the discount.\newlineWhich equation can you use to find pp, the full price of the hotel room per night?\newlineChoices:\newline(A) 7p280=5p7p - 280 = 5p\newline(B) 7p=2805p7p = 280 - 5p\newlineWhat is the full price of the hotel room per night?\newline____ $\$
  1. Set up equation: First, let's set up the equation based on the problem statement. Since the cost for 77 nights with a $280\$280 discount equals the cost for 55 nights without a discount, we write: 7p280=5p7p - 280 = 5p.
  2. Isolate variable: Next, we need to isolate pp. Subtract 5p5p from both sides to get: 2p280=02p - 280 = 0.
  3. Addition step: Now, add 280280 to both sides to solve for pp: 2p=2802p = 280.
  4. Division step: Finally, divide both sides by 22 to find pp: p = rac{280}{2} = 140.
