1. The table provides ages and their corresponding percentiles.
2. The percentile represents the percentage of drivers younger than the given age.
3. The percentage of drivers who are at least a certain age is 100%100\% minus the percentile of that age.

STEP 2

1. Identify the percentile for age 45.
2. Calculate the percentage of drivers who are at least 45.

STEP 3

Identify the percentile for age 45 from the table:
The percentile for age 45 is 5858.

STEP 4

Calculate the percentage of drivers who are at least 45:
100%58%=42% 100\% - 58\% = 42\%
The percentage of drivers who are at least 45 is:
