I recently ordered hair shampoo online. One seller offered Nexxus shampoo for $8.95 per bottle with free shipping. Another seller offered Tresemme for $7.75 per bottle, plus a flat $4.95 shipping fee for the whole order.

Question

1) Write equations for the cost, C, of each option. Please use the letter x for the other variable quantity in this problem.

So I did:
Nexxus: C = 8.95x
Tresemme: C = 7.75x + 4.95

2) Solve the system of equations you wrote above to find the number of bottles of shampoo you would need to buy for the costs to be the same. (Round to the nearest whole bottle)

8.95x = 7.75x + 4.95
Solving, x = 4.125

3) Fill in the blanks:
It would make sense to purchase Nexxus shampoo if you buy _______ than ________ bottles of shampoo?

It would make sense to purchase Tresemme shampoo if you buy _______ than _______ bottles of shampoo?

This is where I am not certain......

Would it be...
It would make sense to purchase Nexxus shampoo if you buy MORE than 4 bottles of shampoo?

It would make sense to purchase Tresemme shampoo if you buy LESS than 4 bottles of shampoo??

I'm pretty confident about answers 1 and 2, just not 3, please help!
