Library 4

Library A has a total collection of 250 books. Library B has 100 more books than Library A, and Library C has twice as many books as the combined number of books in Library A and B. What is the total number of books in libraries A, B and C?

Correct answer:

t =  1800

Step-by-step explanation:

A=250 B=100+A=100+250=350 C=2 (A+B)=2 (250+350)=1200  t=A+B+C=250+350+1200=1800
