A store sells rope by the meter. The equation p=0.8L represent the price p (in dollar) of a price of nylon rope that is L meters long.

Question

How much does the nylon rope cost per meter?

Answer 1

Hi, Ever

 

If p = 0.8L, 

and p is in dollars, then

the cost of the rope is $ .80/meter  ( or 80 cents per meter).

Answer 2

Since the price is 0.8 times L (p=0.8L), the price of rope that is L meters long would just be 0.8L.  Essentially this means that it costs $0.80 per meter.
