Question $3$

Using the chain ratio method, estimate the market sales potential for lung health product to meet the needs of adult smokers. Assume that of the $500,000$ people will suffer from the associated ailments each year, $30\%$ will benefit from these types of products but only $18\%$ of their families have the financial resources to obtain such treatment. Also assume the average price for a device is $$2,800$ but since people have two lung, they will need $2$ products per procedure. Round to the nearest dollar.
