Final answer:
The number of pounds of caffeine being consumed each day is 107.47 lb.
Explanation:
To find the number of pounds of caffeine being consumed each day, we need to multiply the average number of cups of coffee consumed per day by the amount of caffeine in each cup. According to the question, the average coffee consumption is 4.00 x 10^8 cups per day and each cup contains 122 mg of caffeine.
To convert the caffeine from milligrams to pounds, we need to use the conversion factor 1 pound = 453592 milligrams. So, we can calculate the number of pounds of caffeine consumed by dividing the total amount of caffeine in milligrams by this conversion factor:
Total amount of caffeine in milligrams
= (4.00 x 10^8 cups/day) x (122 mg/cup)
= 4.88 x 10^10 mg/day
Number of pounds of caffeine consumed
= (4.88 x 10^10 mg/day) / (453592 mg/lb)
= 107.47 lb/day
