HELP PLEASE



A toy store advertises a sale on a popular children's game during the month of October. The number sold, N, is a function of the amount spent on advertising: where x is in dollars.

22. What is the meaning of the statement f(1000)=50?

23. Assume that f(1000)=50 , and it's also true that the cost to the consumer of each item is $5, did the retailer make wise use of the store's advertising budget? Explain your thinking.

22. N=50 is the number sold.
x=1000 is the sum spent on advertising.
Spending on advertising $ 1,000, the retailer sells 50 games.
23. The retailer didn't make wise because spending on advertising $ 1,000, he gets only $ 250.
