    Answer:

    3.125 mg/ oz

    Step-by-step explanation:

    Amount of instant tea = 24 ounces

    Amount of green tea = 12 ounces

    Caffeine in instant tea = 24/8*30= 90 mg/oz

    Also, caffeine in green tea = 12/8*15 =22.5 mg/oz.

    Total amount of mixture= 24+12= 36 ounce

    Total amount of caffeine in the mixture = 90+22.5 = 112.5 mg/oz

    Caffeine per ounce in the final mixture = 112.5 / 36 = 3.125 mg/ oz
