You can put this solution on YOUR website!
Number of machines x Rate x Time = Output
5%2AR%2A6=4500
R=150
So then,
N%5B2%5D=8%2A150%2A20=24000

1)Five machines can produce 4500 cans of milk in 6 hours, then
4500/6 = 750 cans of milk per hour and each machine produces 750/5 = 150 cans of milk per hour
2) Now we have 8 machines, therefore
8 * 150 * 20 = 24000 cans of milk in 20 hours
