The cost per barrel and retail price of a detergent are 10 yuan and 12 yuan respectively. The cost of each bottle of detergent is 1.2 yuan, and the retail price is 1.5 yuan. There are two options for launching the "Welcome the Spring Festival" commodity preferential activities recently:

Option 1: reduce the price of each barrel of detergent by15%;

Option 2: sell at the original retail price, buy a bucket of detergent and give it away for free 1 small bottle of detergent.
