Question

There were a total of 800 novels and non-fiction books at a book shop. 2/5 of these books were novels. Each novel was priced at $7 and each non-fiction book was priced at $5. How much money would the book owner make if he sold 3/8 of the novel and 2/5 of the non-fiction books?

PLEASE ANSWER FAST!

Answer 1

800*2/5=320 novels
800-320=480 non fiction books

320*3/8=120 novels sold
120*7=$840

480*2/5=192 non fiction books sold
192*5=$960

$960+$840=$1800
The owner would make $1800
