Stream-of-consciousness: Each bag makes a profit of 8 - 4 = $4. So he makes a total profit of 30 * 4 = $120. <hau> Tambaya: John ya sayi buhunan popcorn na dala 4 kuma ya sayar da dala 8. Yaya yawan ribar da yake samu daga sayar da buhu 30? Gudun hankali: Kowace jaka tana samun riba na 8 - 4 = $ 4. Don haka yana samun ribar da ta kai 30*4 = $120.
