Answer:

Step-by-step explanation:

b and p are the number of books and pens, respectively.

“books for 3 dollars each and pens for 4 dollars each. total cost was 60 dollars“

3b + 4p = 60

“he ended up with double the number of books than pens”

b = 2p

3(2p) + 4p = 60

10p = 60

p = 6

b = 2p = 12
