number of seniors 343 368 302
seniors with a license 223 238 197

1. what pattern is there between the number of seniors and the seniors who have a drivers license?
2. the class of 2025 has 420 seniors. how many seniors in the class of 2025 would be expected to have a drivers license?

(round to the nearest integer as needed.)
a each year, about seniors do not have a drivers license.
b each year, about 65% of the senior class have a drivers license.

1. about seniors in the class of 2025 would be expected to have a drivers license.

(round to the nearest integer as needed.)

Explanation:

Step1: Calculate the percentage of seniors with license for each year

For 2021: $\frac{223}{343}\times100\%\approx 65.01\%$; For 2022: $\frac{238}{368}\times100\%\approx 64.67\%$; For 2023: $\frac{197}{302}\times100\%\approx 65.23\%$. The pattern is that about 65% of the senior - class have a driver's license.

Step2: Predict the number of seniors with license in 2025

If 65% of the 420 - senior class of 2025 are expected to have a driver's license, then the number is $420\times0.65 = 273$.

Answer:

1. Each year, about 65% of the senior class have a driver's license.
2. 273
