A local video game store randomly surveyed 80 customers that visited last months about the type of video game they bought. The manager finds that 3 customers bought racing games. If there are 345 customers that visited that month, approximately how many of them bought racing games?

Answer 1

To find out approximately how many of the 345 customers bought racing games, we can set up a proportion using the survey results.

3 customers out of 80 surveyed bought racing games, so we can set up the proportion as follows:

3/80 = x/345

Cross multiplying, we get:

80x = 3 * 345
80x = 1035
x = 1035/80
x ≈ 12.94

Therefore, approximately 13 of the 345 customers bought racing games.
