Michael just drank a cup of coffee to him stay awake. the coffee had 110 milligrams of caffeine in it. if his body processes 5% of the caffeine every hour, how much will be left in 8 hours? a. 74b. 73c. 72d. 56

the answer is 74 goodluck

First take note on the amount he drunk and how much he processes every hour.

Now make a equation

To find the amount he processes do the following

first make the percent a decimal. to do so move the . over to the left two times.

110(.05)= 5.5

He processes 5.5 milligrams per hour now add it up

by multiplying 5.5 by 8

8(5.5)=44

So he processed 44 Milligrams in 8 hours

now subtract 44 from 110 to get whats left

110-44=66

So the answer would be 72
