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
