college algebra homework help please So the chapter is on logarithmic functions and I'm having trouble with this problem: An ulcer patient has been told to avoid acidic foods. If he drinks coffee, with a pH of 5.0, it bothers him, but he can tolerate both tap water, with a pH of 5.8, and milk, with a pH of 6.9. a) What pH will the half coffee-half milk mixture have? ---> I already got this answer, which was a pH of 5.295 b) In order to make 18 oz of a milk-coffee drink with a pH of 5.8, how many ounces of each are required? I need help with part b^ Any and all help is appreciated! :)
