I hope this helps you, let me know if you need more clarification. Also, it's supposed to say apples are $0.70 per pound.
Get rid of parenthesis.
z + z + 6
Add common terms together.
2z + 6 is an expresssion equivalent to z + (z+6)

Answer:
The situation you are describing can be written as y=2x, or in this case t=2f, for every fragrance purchased there are 2 ounces of lotion that are given. Since the ounces of fragrance are not shown in this question, we can only make the graph on the ounces of lotion for every fragarance purchased. The points of the graph represent that for every fragrance bought, there is twice the amount of that in ounces of lotion. In summary, the rule is t=2f where t would equal purchases of fragrance and f would equal the ounces of lotion.
(If there is any more you would like to add to the question I can answer that.)
