A 3.45-acre lot sells for 50 cents per square foot. What was the selling price?

To calculate the selling price of a 3.45-acre lot sold at 50 cents per square foot, you first need to convert acres into square feet since the price is given per square foot.

One acre is equal to 43,560 square feet. Therefore, to find out how many square feet are in 3.45 acres, you would multiply the number of acres by the number of square feet in one acre:

3.45 acres × 43,560 square feet/acre = 150,282 square feet.

Now that we have the total area in square feet, you can multiply it by the selling price per square foot:

150,282 square feet × $0.50/square foot = $75,141.

Thus, the selling price of the lot is correctly calculated to be $75,141. This confirms that the answer provided is indeed the right calculation based on the given information about area and price per square foot.
