*Suppose you have a budget of 400 dollars for one month. You would like to buy some textbooks and CDs. The average cost of a book is 40 dollars each and that of a CD is 14 dollars each. Let x denote the number of books you buy and y denote the number of CDs that you buy. (a) Write the equation of your budget constraint in the form y=mx+b, where m and b are numbers to be determined. Answer: y= (b) If you decide to buy just one textbook, how many CDs can you afford? Enter the number of CDs as a whole number. Answer: I can buy CDs. Hint: HINT: For part (a), write the budget constaint in the form and then solve that equation for y. cx + dy = 400
