After caffeine is absorbed into the body, 13% is eliminated from the body each hour.  Assume a person drinks an 8-oz cup of brewed coffee containing 130 mg of caffeine, and the caffeine is absorbed immediately into the body.  Using Visual Basic, write a program to calculate the following values.  See the figure below.

1. The number of hours required until 65 mg (one-half the original amount) remain in the body.
2. The amount of caffeine in the body 24 hours after the person drinks the coffee.
3. Suppose the person drinks a cup of coffee at 7 a.m. and then drinks a cup of coffee at the end of each hour until 7 a.m. the next day.  How much caffeine will be in the body at the end of the 24 hours?
