Answer: 45% of the people were satisfied with the car.

Step-by-step explanation:

1. Organize what the text is telling you.

  • Total people who answered survey: 3,100
  • People that answered would buy again: 1,395

2. Now we have to turn this into a fraction so we can turn it into a percentage. But first we'll review what a fraction is.

Review

There are two parts of a fraction: the numerator & the denominator.

  • The numerator represents how much is in the total, and the denominator is the entire data or total.
  • The numerator is on top of the fraction line, and the denominator is on the bottom of the fraction. [tex]\frac{numerator}{denominator}[/tex]

Application

  • 1,395 is the numerator because it is a portion of the total. 3,100 is the total, so it is the denominator.
  • We would put 1,395 on the top of the fraction and 3,100 on the bottom of the fraction. [tex]\frac{1395}{3100}[/tex]

3. Now we take this fraction, [tex]\frac{1395}{3100}[/tex], and turn it into a decimal.

  • To turn a fraction into a decimal, divide the top number by the bottom, 1395 by 3100, and we get 0.45.

4. Now we turn this decimal, 0.45, into a percentage.

  • To turn a decimal into a percentage, multiply the decimal by 100 and add %.
  • 0.45 x 100 = 45%.

5. 45% of the people were satisfied with the car.
