During peak season, a hotel room costs $135 per night. During the offseason, it costs $90 pernight. Find the percent of change from peak season to offseason.

Math 
Ms. Sue,
1. Subtract the difference in costs (135  90)
2. Divide the original cost by the difference between the two costs.
3. Change the decimal to a percent.
If you post your answer, we'll be glad to check it.

Brandon,
30%?

Ms. Sue,
Sorry, but I was wrong in step 2. You should divide the difference by the original cost.
45/135 = 0.3333 = 33%
Offseason is 33% lower than peak season.
