A local video game store randomly surveyed 80 customers that visited last month 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?

1 answer

To find the approximate number of customers who bought racing games, we can set up a proportion using the number of customers surveyed who bought racing games.

Let x be the unknown number of customers who bought racing games out of the 345 total customers.

We know that 3 out of 80 customers surveyed bought racing games. So we can set up the following proportion:

3/80 = x/345

Cross multiplying, we get:

80x = 3 * 345
80x = 1035
x = 1035 / 80
x = 12.9375

Since we cannot have a fraction of a customer, we round up to the nearest whole number. Therefore, approximately 13 customers out of the total 345 bought racing games.
