Given the statement:
Davis notcies that his hair is decreasing exponentially at a rate of 10% per year. If he starts with 100,000 hairs on his head
Determine the remaining amount after 3 years.
Solution:
In order to determine the remaining amount, we will use the formula,
Remaining amount= 100,000(1-0.1)^3
Remaining amount= 100,000(0.9)^3
Remaining amount= 100,000(0.729)
Remaining amount= 72,900
Final answer:
The remaining har is 72,900.
