If Wang Shibo can produce at most 8 pieces of protective clothing every day, how many days will it take to produce 50 pieces?

Seven days. Wang Shibo wants to produce 50 pieces of protective clothing, with a maximum of 8 pieces per day. On the sixth day, he has already paid 6×8=48 yuan, and he is still short of 2 yuan and 50 yuan. These two pieces need to be produced on the seventh day. Therefore, if Wang Shibo wants to produce 50 pieces of protective clothing, it will produce 8 pieces at most every day, and it will take 7 days at the earliest.
