Michael and Thomas are selling their lego collections. They agree to split any money they earn. They sell them based on how many circles are on top. Each circle costs 1 cent. They earned $5 each after selling 100 single pieces, 45 double pieces, 50 triple pieces and a number of quadruple pieces. How many quadruple pieces did they sell?
They made $10 because 2 x 5 = <<2*5=10>>10
They made $1 off single pieces because 100 x .01 = <<100*.01=1>>1
They made $.9 off double pieces because 45 x .02 = <<45*.02=.9>>.9
They made $1.5 off triple pieces because 50 x .03 = <<50*.03=1.5>>1.5
They earned $3.4 off the first three types because 1 + .9 + 1.5 = <<1+.9+1.5=3.4>>3.4
They earned $6.6 off the quadruple pieces because 10 - 3.4 = <<10-3.4=6.6>>6.6
They sold 165 quadruple pieces because 6.6 / .04 = <<6.6/.04=165>>165

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:

John's neighbor tells him to walk his dog for 1 hour each day for a total of $10. He does this for April, save for the 4 Sundays in April. He later spent $50 on books and gave his sister Kaylee the same amount. How much money did John have left?April has 30 days, so if he didn't walk the dog on Sundays, he worked for a total of 30 days - 4 days = <<30-4=26>>26 days.
If each day he earned $10, he ends up with 26 days * $10/day = $<<26*10=260>>260 .
After buying books and giving his sister $50, he ends up with $260 - $50 - $50 = $<<260-50-50=160>>160

A school is adding 5 rows of seats to the auditorium. Each row has 8 seats and each seat costs $30. A parent, being a seat manufacturer, offered a 10% discount on each group of 10 seats purchased. How much will the school pay for the new seats?Ten seats amount to $30 x 10 = $<<30*10=300>>300.
So there is $300 x 10/100 = $<<300*10/100=30>>30 discount for each 10 seats purchased.
Thus, the total cost for every 10 seats is $300 - $30 = $<<300-30=270>>270.
The school is going to buy 5 x 8 = <<5*8=40>>40 seats.
This means that the school is going to buy 40/10 = <<40/10=4>>4 sets of 10 seats.
Therefore, the school will pay a total of $270 x 4 = $<<270*4=1080>>1080 for the new seats

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

Michael and Thomas are selling their lego collections. They agree to split any money they earn. They sell them based on how many circles are on top. Each circle costs 1 cent. They earned $5 each after selling 100 single pieces, 45 double pieces, 50 triple pieces and a number of quadruple pieces. How many quadruple pieces did they sell?

### Response:
They made $10 because 2 x 5 = <<2*5=10>>10
They made $1 off single pieces because 100 x .01 = <<100*.01=1>>1
They made $.9 off double pieces because 45 x .02 = <<45*.02=.9>>.9
They made $1.5 off triple pieces because 50 x .03 = <<50*.03=1.5>>1.5
They earned $3.4 off the first three types because 1 + .9 + 1.5 = <<1+.9+1.5=3.4>>3.4
They earned $6.6 off the quadruple pieces because 10 - 3.4 = <<10-3.4=6.6>>6.6
They sold 165 quadruple pieces because 6.6 / .04 = <<6.6/.04=165>>165
