Answer:
Tires that wear out by approximately 24307.8 miles will be replaces free of charge.
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 27,000 miles
Standard Deviation, σ = 2100 miles
We are given that the distribution of life expectancy is a bell shaped distribution that is a normal distribution.
Formula:

We have to find the value of x such that the probability is 0.10
Calculation the value from standard normal z table, we have,
Tires that wear out by approximately 24307.8 miles will be replaces free of charge.
Formula= amount=principal(1+rate/100)^time
a=3000(1+2.5/100)^5
a=3000(100/100 +2.5/100)^5
a=3000(102.5/100)^5
a=3000(1.025)^5
a=3000x1.131408212890625
a=3000x1.1314
a=3394
