Logan asked his 20 coworkers whether they own a car or a truck. There were 6 more car owners than truck owners. How many people owned a car?
A) 7 people
B) 9 people
C) 11 people
D) 13 people
Say x is the number of truck owners.
Then the number of car owners would be x+6
Since all of Logan's coworkers either own a car or a truck, the equation would be x+x+6=20
which is equal to
7+6= 13 , so 13 people owned a car
