Respuesta :
You calculate the number of delivered mails in one month then multiply it with 2.
8520 / 12 = 710 (12 months in a year)
710 * 2 = 1420
8520 / 12 = 710 (12 months in a year)
710 * 2 = 1420
The answer is 1420 because 8,520 divided by 12( there is 12 months in a year) is 710 that means each month he delivers 710 pieces of mail. Then, multiply it by 2 ( for the 2 months) and you get the product of 1420.
