Hi there,
The equation to this is going to be : c = 3r - 3s
If you want to get the lower price down you are going to have to buy 3 shampoo bottles in order to get a lower price. The cost you save is the main difference from a regular price. And the answer is c = 3r - 3s
Just add the two equations.
8x-3y=22
I hope this helps :)
