Work Step by Step
Total number of people who would consider buying an electric car if it will go 300 miles or more between charges = 21% (300 mile)+ 34%(400 miles and more)
the percent equation. part = percent * whole
Total number of people are 3021 so the whole is 3021
The percent is 55% or, as a decimal, 0.55. Find the part.
Part = percent * whole
= 0.55 * 3021
= 1661.55 people = 1662 people(rounded)
