How much will Sam pay for his portion of sidewalk construction at $7.50 per front foot?

To determine how much Sam will pay for his portion of sidewalk construction at a rate of $7.50 per front foot, it is crucial to know the total number of front feet that apply to his portion. The calculation involves multiplying the cost per front foot by the number of front feet.

If Sam's portion of the sidewalk is 105 front feet, the calculation would be:

Total Cost = Number of Front Feet × Cost per Front Foot Total Cost = 105 feet × $7.50/foot = $787.50

This calculation indicates that, given the scenario, Sam's total cost aligns with the chosen answer. Understanding how to break down costs according to front footage and applying the rate is essential in real estate transactions involving construction or improvements to property.

The other answers reflect either miscalculations or incorrect assumptions regarding the number of front feet assigned to Sam's responsibility. Therefore, identifying the correct unit measurement and rate is vital in arriving at the accurate total.
