QUESTION:
if 4 books of the same type cost 1320 what is the cost of 12 such books
ANSWER:
4 books cost 1320
We want to know the price for 12 books. We can either calculate the piece for 1 book and then multiply it by 12 or calculate how many times the set of 4 books repeats in 12 books
12÷4 = 3
The quantity of 12 books is 3 times greater than of 4 books that means, that the price for 12 books is also 3 times greater than the price for 4 books
1320×3 = 3960
