Answer:
Explanation:
It is wrong to assume a proportional increase of the license revenues with the price.
The revenue is the product of the number of fishing lines and the price.
The fishing licenses are not an essential good, so its demand is elastic.
Assuming that the number of fishing licenses to sell at the new price, $2 greater than the last year's price, will be the same as the number of fishing licenses sold the last year is a wrong assumption, because the demand should be expected to decrease.
The elasticity of the demand states that as the price of a not essential good increases, it demands will decrease, because the public will prefer another good. For instance, the public might start birding.
