Question

The normal healing of wounds can be modeled by an exponential function. If A0 represents the original area of the wound and if A equals the area of the wound after n days, then the formula below describes the area of a wound on the nth day following an injury when no infection is present to retard the healing.

A = A0*e-0.33n

Suppose that a wound initially had an area of 100 square millimeters.

(a) If healing is taking place, how long will it be before the wound is exactly one-half its original size?
_____days

(b) How long will it be before the wound is exactly 10% of its original size?
_____days
