Final answer:
To find the price of the lot, multiply the area by the price per front foot.
Step-by-step explanation:
To find the price of the lot, we need to calculate the total area first. The area of a rectangle is given by multiplying its length and width. Here, the length is 240 feet and the width is 400 feet, so the area is 240 x 400 = 96,000 square feet.
To find the price, we need to multiply the area by the price per front foot. The price per front foot is $400. So, the total price is 96,000 x $400 = $38,400,000.
Therefore, the correct answer is a) $960,000.
