The city would like to install a concrete walkway between the soccer field and restaurant. They have budgeted $4,000 for this walkway. The concrete needed to create the walkway costs $315 per mile but the city is getting a bulk discount of $125 off every 3 miles. Any additional concrete that is not part of a 3-mile bundle will be charged the full price. Determine the price of the walkway. Is the city is over or under budget?
