Question

The expression 80x + 500 represents the cost in dollars of the materials and laborneeded to build a square fence with side length, x, feet around a playground. What doesthe coefficient of x represent?

Answer 1

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

Step-by-step 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.
