The pie chart below represents the vehicle types owned by families. If the total number of people surveyed is 1000, approximately how many own a van?

Answers

Answer:

500 families

Step-by-step explanation:

We want to estimate the size of the dark blue section of the chart. The chart looks like the left of the pie chart is split evenly with the dark blue section. So we estimate that each of those must represent 12 or 50% of the total number of families. Therefore,

0.50⋅1000=500

About 500 families own a van.
