Answer:
it will cost 90 cents for 6 books
Explanation:
if 2 books cost 30 cents then each book cost 15 so 2 books will be 30 cents so what that means is that each book is 15 cents so if u times 6 × 15 it will be 90
6= books
15= cents
90= cost
90 cents
If 2 books cost 30 cents, then that means each book costs 15 cents. Then you can do 15 (cents) x 6 (books) = 90 cents
