Question

A survey shows that 17% of car owners have their car’s oil changed every 4 months. Out of 1205 car owners, how many would you predict would have their car’s oil changed every 4 months?

Answer 1

We predict that 205 car owners would have their car’s oil changed every 4 months

Explanation:

Since 17% of car owners have their car's oil changed every 4 months,

So, 17% of the 1205 car owners would have changed their car's oil every 4 months, that is,

17% of 1205,

(17/100)(1205) = 0.17(1205) = 204.85

Rounding to a whole number, we get, 205 car owners
