we have given that the a mixture consisting of 24 ounces of instant tea and 12 ounces of green tea.
And we have to find that the milligrams of caffeine per ounce were in this final mixture.
So, For this purpose, we know that the
Ounce is a unit of weight equal to one sixteenth of a pound
Amount of instant tea = 24 ounces
Amount of green tea = 12 ounces
Caffeine in instant tea = 40 mg / 8 fl. oz. = 5 mg/fl.oz.
Caffeine in green tea = 25 mg /8 fl. oz. = 3.125 mg/fl.oz.
Caffeine in 24 ounces of instant tea = 5* 24 = 120 mg
Caffeine in 12 ounces of green tea = 3.125 * 12 = 37.5 mg
Total amount of the mixture = 24 + 12 =36 ounces
Total amount of caffeine in the mixture = 120 + 37.5 = 157.5 mg
Caffeine per ounce in the final mixture = 157.5 / 36 = 4.375 mg/ fl.oz
