Question

Jorge finds that 56% of his 75 classmates like salsa music and 80% of his 60 relatives like salsa music. How many more of Jorge's relatives,as compared to his classmates, like salsa music?

Answer 1

6 more

Explanation:

Find 56% of 75 first

75/x=100/56

(75/x)*x=(100/56)*x

75=1.78571428571*x

(1.78571428571) to get x

75/1.78571428571=x

42=x

x=42

Then Find 80% of 60

60/x=100/80

(60/x)*x=(100/80)*x

60=1.25*x

60/1.25=x

48=x

x=48

Subtract 48 by 42
