Logan's father receives 50 cartons delivery for his milk business, each carton having 20 jars of milk. On a particular week, he received 20 cartons less when the delivery was done, and during offloading, he realized 3 jars in 5 cartons each was damaged, and one carton was totally damaged. How many jars of milk were good for sale that week? Let's answer step by step:
When 20 cartons failed to be delivered, the number of cartons reduced to 50 - 20 = 30 cartons. The total number of jars in all the cartons is 30 * 20 = 600. The total number of jars destroyed in the 5 cartons is 3 * 5 = 15 jars. If one carton was also destroyed, the total number of destroyed jars is 20 + 15 = 35 jars. The number of jars good for sale is 600 - 35 = 565 jars. The answer: 565.
