Ast year prom tickets were $65, and this year they are $50. what is the percent of decrease in the price of prom tickets? round to the nearest whole percent. a) 15% b) 23% c) 30% d) 52%

Using [(65 - 50) / 65] * 100, we can find our answer and round.

[(65 - 50) / 65] * 100 = ?
[15 / 65] * 100 = -0.230769231 * 100

= 23.0769--

Now, just round that to 23 and you get 23%.
Hope that helped!
