### Instruction:
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?

### Response:
 Masanduku 20 yaliposhindwa kusafirishwa, idadi ya masanduku ilipungua hadi 50-20=<<50-20=30>>30 masanduku.
Idadi jumla ya vikombe katika masanduku yote ni 30*20 = <<30*20=600>>600
Idadi jumla ya vikombe vilivyoharibiwa katika masanduku 5 ni 3*5 = <<3*5=15>>15 vikombe
Idadi jumla ya vikombe vilivyoharibiwa katika sanduku lililoharibiwa kabisa ni 20.
Idadi ya vikombe vizuri ni 600-15-20= <<600-15-20=565>>565 vikombe.
