If Adam buys 4 books, it will cost him $20 (4 x $5 = $20), leaving no money for pencils. If he buys 1 book it will cost him $5, so he has $15 left for pencils. With $15 he can buy 30 pencils (30 x $0.50 = $15). If he buys 2 books, it will cost him $10, leaving $10 for pencils. With $10 he can buy 20 pencils (20 x $0.50 = $10). Therefore, the bundle of 2 books and 30 pencils is not affordable for Adam as it would cost him $20 (2 x $5 + 30 x $0.50 = $20), which is more than his monthly income.
