Asurvey showed that 56% of car owners prefer four-door cars, 31% prefer two-door cars, and 13% have no preference. you ask 300 people. how many do you think will prefer four-door cars?

I believe that its 168 people prefer four door cars

Alright, if you have 300 people you need to find what 56% of that 300 is. The first thing you need to do is follow the converting a percentage to decimal rule; which just states that you need to move the decimal place two to the left, so you will go from 56. to .56. 56% is .56 as a decimal. Now you have to multiply the decimal by the 300 people. So, 300 x .56 = ? We get 168. 168 people prefer four-door cars. 

The answer is a isosceles triangle
