A national park remains track of how many people per car enter the park. Today, 57 cars had 4 people, 61 cars had 2 people, 9 cars had 1 person, and 5 cars had 5 people. What is the average number of people per car? Round to the nearest person.
Find out the total number of people and the total number of cars. After that, divide the total people through the total cars.
People: 57 × 4 = 228
61 × 2 = 122
9 × 1 = 9
5 × 5 = 25
TOTAL 384 people
Cars: 57 + 61 + 9 + 5 = 132
384 ÷ 132 = 2.9 which is rounded up to 3 people since 2.9 is closer to 3 than it is to 2.
