2. Ha bought 2 dozens of pencils for 30 000 VND. If Mai wants to buy 8 pencils of the same kind,...

Therefore, Mai needs to pay 10,000 VND to buy 8 pencils of the same kind.

Mai wants to buy 8 pencils, so she needs to pay 8 pencils x 1,250 VND = 10,000 VND for the 8 pencils of the same kind.

To find the price of 1 pencil, we divide the total price by the number of pencils, so 30,000 VND / 24 pencils = 1,250 VND per pencil.

Ha bought 2 dozens of pencils, which means he bought 2 x 12 = 24 pencils for 30,000 VND.
