30d

To find out how much Brown will earn, we can multiply the number of candies he sells by the amount he earns for each candy.

Given:
Number of candies sold (n) = 30
Amount earned per candy (a) = 1 dollar

To calculate the total amount earned, we use the formula:
Total amount earned = Number of candies sold * Amount earned per candy

Substituting the given values:
Total amount earned = 30 * 1
Total amount earned = 30 dollars

Therefore, Brown will earn 30 dollars by selling 30 candies.
