Answer 1

The caffeine per ounce in the final mixture of green and instant tea is 40.08 mg.

Based on the data we know quantity of caffeine in an ounce of instant tea is 1368 mg and in green tea is 480.96 mg. So, calculating amount of caffeine in instant and green tea.

Amount of caffeine in instant tea = 24 × 57

Amount of caffeine in instant tea = 1368 mg

Amount of caffeine in green tea = 12 × 6.25

Amount of caffeine in green tea = 75 mg

Total caffeine in the mixture = 1368 + 75

Total caffeine in the mixture = 1443 mg

Total amount of mixture = 12 + 24

Total amount of mixture = 36

Amount of caffeine per ounce in the mixture = 1443/36
