Answer:
$1,443.75
Explanation:
The total cost for paving Sam's portion of the road = $35 per linear foot x 110 front feet = $3,850
If the city is going to pay 25% of the total cost, then it will pay $962.50, that would leave a total of $2,887.50 to be paid between Sam and his front neighbor. So Sam's share = $2,887.50 / 2 = $1,443.75
