Respuesta :

ANSWER

The cost increases $80 per 1 foot increase in side length.

EXPLANATION

If 'x' represents the side length of the fence, its coefficient represents how much each foot of that length costs.

Then 500 is the up-front of the project. If they build a fence with a side length of 5 feet or 500 feet, the cost will be at least $500 - then we'll have to add the cost to each foot of fence.
