Question

how to solve

Answer 1

What do you need to find out? The amount you have to spend? From what I'm gathering from the question all you have to do is break the question down. Here's a simple way

 

for every three bars of soap purchased one is given free the bars of soap cost $2 each and there is a limit of 8 bars of soaps including free ones

 

3 bars: 1 free

3 bars: 1 free

 

6 paid bars: 2 free

 

6 times $2 equals $12 for 6 paid bars plus 2 free bars 

 

So you have 8 bars of soap for $12.
