Answer:
7875 parts
Step-by-step explanation:
#Find the number of parts cut by the machine per hour:
[tex]=105\times \frac{60\ min}{3\ min}\\\\=2100\ parts[/tex]
#Find the number of parts per machine per hour:
[tex]p/m/h=\frac{2100}{6}\\\\=350\ parts[/tex]
#Given that only 5 machines are now working for 4.5 hrs, we calculate the total parts as:
[tex]Parts=p/m/h\times\times \ number \ of \ machines \times time\\\\=350\times 5\times 4.5\\\\=7875\ parts[/tex]
Hence, the total parts cut by 5 machines is 7875 parts
