The price of concert ticket dropped from $177 to $91. What was the precent of decrease in price of tickets? PLEASE HELP ASAP

Answer:
The percent of decrease can be calculated with this formula:
(Original value - New Value)/(Original Value)
In this case, the original value is 117 and the new value is 91.
So the percent of decrease is 26/117, or about 22%.
Hope this helps!
