What is the mean sales price of the nine houses sold by Martin with prices given?

To find the mean sales price of the nine houses sold by Martin, you need to determine the total sales price of all the houses and then divide that sum by the number of houses sold.

The mean, or average, is calculated using the formula:

Mean = (Sum of all sales prices) / (Number of houses)

So, if you add up the prices of the nine houses and find that their total equals 1,873,998, you would divide that amount by 9, which gives you approximately 208,222.

Thus, the mean sales price of $208,222 is correct because it accurately reflects the total sales distributed over the number of houses sold. This approach is crucial as it ensures that you consider every property equally when estimating an average price, leading to a fair representation of the market value for this specific set of sales.
