John, Kevin and Steve have a total of 112 books. Kevin has 9 times more books than john. Steve has 4 times more books than john. How many books does Kevin have?

Relevance

Let's call the number of books John has x. John has x books. Keven has 9x books. Steve has 4x.

So add them up. x + 9x + 4x = 112. 14x = 112. 112/14 = x.

112/14 = 8. So Kevin has 8 books.

• J is Johns amount

9J would be Kevin’s

4J is Steve

J plus 9J plus 4J equals 112.

solve for J and then you can get K.

• J + k + s = 112

K = 9j

S = 4j

Just sub. 9j + 4j + j = 112

14j = 112

J = 8

K = 9j = 9(8) = 72
