Answer 2

There is increased percentage of 8% in the income.

Step-by-step explanation:

Since we have given that

Rate of growth in the price of ticket = 20%

Rate of decline in the price of ticket = 10%

So, Net change in percentage would be

$x-y-\dfrac{xy}{100}\\\\=20-10-\dfrac{20\times 10}{100}\\\\=10-2\\\\=8\%$

Hence, there is increased percentage of 8% in the income.
