Jake has twice as many books as Bob. Pete has B more books than Bob Bob has B books. How many books do the three boys have althogether in terms of B ?

Sagot :

Let B be the number of books Bob has.

Since it is said that Jake has twice the number of books Bob has, we can say that Jake has a number of books given by 2B.

Pete has B more books than Bob has, which can be said as B+B, which is also 2B.

For simplicity:
B=Bob books
2B=Jake books
2B=Pete books


Therefore, if we add Bob's, Jake's and Pete's books, we get:
B+2B+2B=5B

Hope that helps.
