Here,
Let the usual fee be = 100

SO 1st concert 12.5% less than usual fee = 87.5

Now 2nd concert 20% greater than 1st concert = 87.5 + 17.5 = 105

Now New fee greater than usual fee = \(\frac{(105-100)}{100}\) = 5%

We can let her usual fee = 1000, so the fee for her first concert was 0.875 x 1000 = 875, and the fee for her second concert was 1.2 x 875 = 1,050. Now we need to determine what percent greater the fee for the second concert was compared to the usual fee.

(1,050 - 1000)/1000 x 100

50/1000 x 100 = 50/10 = 5 percent

Answer: A
