Question

You are looking at dish soap that is on sale for buy one, get one free. The soap normally costs $2.78 per bottle. You decide to get 3 bottles. If sales tax is 6%, how much is your total?

Answer 1

I believe $5.89
because: you take $2.78 and multiply it by 6% (.06) and get .1668 then you add that to $2.78 leaving you with $2.94 then you will multiply that by 2 since you are buying 3 soaps but one is free so therefor you will multiple the soap cost by 2 instead of 3
