Newspaper profit

Question

A newspaper's profit is $20 per year for each of its 2,500 subscribers. Management estimates that the profit per subscriber will increase by 1¢ for each additional subscriber over the current 2,500. How many subscribers will bring a total profit of $180,000?

Answer 1

If the first 2500 subscribers each yield a $20 profit, the total profit is $50,000

 

Let x = the number of additional subscribers beyond the first 2500

 

We have

 

50,000 + .01x = 180,000

 

.01x = 130,000

 

x = 13,000,000 

 

It will take 13 mil additional subscribers to reach $180,000 in total profits
