A factory decides to stop making cars and start making motorcycles instead. When it made cars, per month, it cost $100 for materials, they could make 4 cars, and they sold each car for $50. Now that they make motorcycles it costs $250 for materials, but they sell 8 of them for $50 each. How much more profit do they make per month selling motorcycles instead of cars?
They sold $200 worth of cars each month because 4 x 50 = <<4*50=200>>200
They made $100 a month off cars because 200 - 100 = <<200-100=100>>100
They sold $400 worth of motorcycles each month because 8 x 50 = <<8*50=400>>400
They make $150 a month off motorcycles because 400 - 250 = <<400-250=150>>150
They make $50 more a month off motorcycles than cars because 150 - 100 = <<150-100=50>>50

Below is an instruction that describes a task. Write a response that appropriately completes the request.

### Instruction:
You are solving math problems. Here are some examples of how to solve the task:

Joe saves $6,000 for his trip to Australia. If he spends $1,200 on the flight, $800 on a hotel, and $3,000 on food, how much money, in dollars, does he have left?Joe spends 1200+800+3000=<<1200+800+3000=5000>>5000 dollars.
Joe has 6000-5000=<<6000-5000=1000>>1000 dollars left.

Dylan's mother is throwing a baby shower for her best friend. She is expecting 40 guests, of whom she has cleared the parking lot to park in to, leaving only her car and her husband's jeep in the parking lot. The 40 guests, though, arrive in only 10 cars that they park in the parking lot.  If each car has 4 wheels, how many car wheels are there in the parking lot, including both of Dylan's parent's car wheels?10 cars are parked around for the party, 10 x 4 wheels each car = <<10*4=40>>40 wheels total.
Dylan's parents both have a car with 4 wheels each, 2 x 4 = <<4*2=8>>8 more wheels.
Combined, there are 40 + 8 = <<40+8=48>>48 wheels total on the Dylan family property.

Now, solve this next question in the style of the above examples:

A factory decides to stop making cars and start making motorcycles instead. When it made cars, per month, it cost $100 for materials, they could make 4 cars, and they sold each car for $50. Now that they make motorcycles it costs $250 for materials, but they sell 8 of them for $50 each. How much more profit do they make per month selling motorcycles instead of cars?

### Response:
They sold $200 worth of cars each month because 4 x 50 = <<4*50=200>>200
They made $100 a month off cars because 200 - 100 = <<200-100=100>>100
They sold $400 worth of motorcycles each month because 8 x 50 = <<8*50=400>>400
They make $150 a month off motorcycles because 400 - 250 = <<400-250=150>>150
They make $50 more a month off motorcycles than cars because 150 - 100 = <<150-100=50>>50
