Final answer:
The percentage decrease in room rate from $160 to $150 is 6.25%. This is found by subtracting the new rate from the original, dividing by the original rate, and multiplying by 100.
Step-by-step explanation:
To calculate the percentage decrease in your average room rate, you need to subtract the new rate from the original rate, divide the result by the original rate, and then multiply by 100 to get the percentage.
Original rate = $160/night
New rate = $150/night
Subtract the new rate from the original rate: $160 - $150 = $10 decrease.
Next, divide the decrease by the original rate: $10 / $160 = 0.0625.
Finally, multiply by 100 to find the percentage decrease: 0.0625 * 100 = 6.25%.
So the rate decrease percentage is 6.25%.
