Answer

Explanation:

Step1: Calculate the percentage of seniors with license each year

For 2021: $\frac{273}{343}\times100%\approx79.6%$; For 2022: $\frac{238}{360}\times100%\approx66.1%$; For 2023: $\frac{197}{302}\times100%\approx65.2%$; For 2024: $\frac{245}{379}\times100%\approx64.6%$. The percentages are relatively close.

Step2: Select the pattern

The pattern is that each year, about a certain percentage of the senior - class have a driver's license.

Step3: Calculate the expected number for 2025

First, find the average percentage of seniors with license. $\frac{79.6 + 66.1+65.2 + 64.6}{4}\times100%\approx68.9%$. If there are 420 seniors in 2025, the expected number of seniors with license is $420\times0.689 = 290.38\approx290$.

Answer:

  1. B. Each year, about 69% of the senior class have a driver's license.
  2. 290
