I’m confused becoz only equal to 180 makes sense....how can it be less than 180

[holdthephone]

Can I ask something. I did it differently, but I dont know if I did it correctly. Technically it takes 6 min to do 6 envelopes because of 50 seconds added on to each envelope. so that being, 180/6 = 30 * 6 which equals 180. So N = 180 right?
