Question

Amanda, Bryan, and Colin are in a book club. Amanda reads twice as many books as Bryan per month and Colin reads 4 fewer than 3 times as many books as Bryan in a month. In 4 months the number of books Amanda reads is equal to 5/8 the sum of the number of books Bryan and Colin read in 4 months. How many books does each person read each month?

Answer 1

A=2b C=3b-4. A=5/8x4 = b+cx4 If Brian read let's say 3 books a month then amanda reads 6 and Collin reads 5 So the answer would be B= Brian's books. A= Amanda's books and c= Collins books So a=2xb B=b C=(3b)-4
