If a club made a gross profit of $0.25 for each candy bar it sold, how many candy bars did the club sell?
(1) the total revenue from the sale of the candy bar was $300
(2) if the club had sold 80 more candy bars, its gross profits would have increased by 20%
2. profit from 80 more candies = 80 x 0.25 = 20 which is 20% more form the actual profit.
so the actual profit = 100.
no of candies = 100/.25 = 400
