a survey of autos parked in student and staff lots at a large university classified the brands by country of origin, as seen in the table. complete parts a through f below.
origin \tdriver
\t\tstudent \tstaff
american \t105 \t106
european \t31 \t13
asian \t55 \t49

a) what percent of all the cars surveyed were foreign?
(square%)
(round to one decimal place as needed.)

Explanation:

Step1: Calculate total foreign cars

Foreign cars are European + Asian. For students: \(31 + 55 = 86\). For staff: \(13 + 49 = 62\). Total foreign: \(86 + 62 = 148\).

Step2: Calculate total all cars

American: \(105 + 106 = 211\). European + Asian: \(148\) (from step1). Total: \(211 + 148 = 359\).

Step3: Calculate percentage

Percent foreign: \(\frac{148}{359} \times 100 \approx 41.2\) (rounded to one decimal).

Answer:

\(41.2\)
