Consider the Q and A. Q: If 2 machines in a factory make 10 cell phones each minute, how many machines would it take to make 50 cell phones a minute?
A: 10
What is the step-by-step reasoning process?
Step-by-step reasoning process: First, we need to determine how many cell phones each machine makes per minute. We do this by performing 10 / 2 = 5 cell phones each minute per machine. Next, we determine how many machines are needed in total by dividing the desired outcome of 50 by the rate of production of an individual machine, finding 50 / 5 = 10 machines needed.

Consider the Q and A. Q: Andrew has 2 3-hour appointments today. He spends the rest of his 8-hour workday stamping permit applications. If he can stamp 50 permit applications an hour, how many permits total does he stamp today?
A: 100
What is the step-by-step reasoning process?
Step-by-step reasoning process: First find the total length of the appointments: 2 appointments * 3 hours / appointment = 6 hours. Then subtract that time from the length of Andrew's workday to find how many hours he spends stamping permits: 8 hours - 6 hours = 2 hours. Then multiply that number by the number of permits he can stamp per day to find how many permits he stamps: 50 permits / hour * 2 hours = 100 permits.

Consider the Q and A. Q: A small store made 50 posters to advertise their products. Two-fifths of them are small posters while half of them are medium posters. The rest are large posters. How many large posters are there?
A: 5
What is the step-by-step reasoning process?
Step-by-step reasoning process: 50 x 2 / 5 = 20 posters are small. And 50 / 2 = 25 posters are medium. So 20 + 25 = 45 posters are not large. Therefore, 50 - 45 = 5 posters are large.

Consider the Q and A. Q: Sansa is a famous artist, she can draw a portrait and sell it according to its size. She sells an 8-inch portrait for $5, and a 16-inch portrait for twice the price of the 8-inch portrait. If she sells three 8-inch portraits and five 16-inch portraits per day, how many does she earns every 3 days?
A: 195
What is the step-by-step reasoning process?
Step-by-step reasoning process:
Sansa earns $5 x 3 = $15 every day by selling three 8 - inch portraits. The price of the 16 - inch portrait is $5 x 2 = $10 each. So, she earns $10 x 5 = $50 every day by selling five 16 - inch portraits. Her total earnings is $50 + $15 = $65 every day. Therefore, the total amount she earns after 3 days is $65 x 3 = $195.
