Answer:

cost of 12 books = 600

cost of one book = 600/12

= 50

when increase 30 in total cost = 600+ 30

= 630

the cost of books = 630/50

=12.6

Câu trả lời + Giải thích:

Chi phí của 12 cuốn sách là: 600

Giá của 1 cuốn sách là: 600 : 12 = 50

Khi tăng 30 trong tổng chi phí thì: 600 + 30 = 630

Vậy giá của 1 cuốn sách sẽ là: 630 : 50 = 12,6
