At a store that sells fences, if you buy 15 feet of fencing or less, the total cost, including delivery, is $200. Each additional foot of fencing costs an additional $10. Let F be the number of feet of fencing in an order and let C be the cost (in dollars) of the order.
- What restriction should be made on F so that the relationship between C and F is linear? Explain.
- Withoutwriting an equivalent equation, explain how to interpret each side of the equation below and explain why the equation describes the relationship between F and C (with the restrictions of part [a]).
C- 200 = 10(F 15)
