After the reduction of the stadium entrance ticket price, the number of spectators increased by 25%

After the reduction of the stadium entrance ticket price, the number of spectators increased by 25%, the revenue increased by 12.5%. How much is the admission price reduced?

Let x be the new ticket price.

Then 1 spectator * 1 ticket = there was the proceeds initially.

Hence:

25% = 1.25 viewers;

1.125 = 12.5% of original revenue

1.25 * x = 1.125;

x = 1.125 / 1/25;

x = 0.9;

0.9 = 90% of the original ticket price

100% – 90% = 10%

Answer: the entrance ticket price has decreased by 10%.
