Answer:

Approximate decrease is 70%

Step-by-step explanation:

The percent decrease is the change over the new original / final value.  The change between the old and the new is 850 - 500, which is 350.  Thus the approximate percentage difference is

<u>350</u>

500

A quick way to turn anything with a denominator that starts with 5 and any number of zeros after it ... is to multiply both the top and bottom by 2.  That is, that turns the ratio above to:

<u>700 </u>

1000

Since a percentage is a number of 100, not 1000, just divide everything by 10.  That means take away a zero from each number, which gives you a fraction of:

<u>70 </u>

100

Thus, the result is 70/100, or 70%.

nataly862011 [7]

Answer:

x  =  2000 cameras

Step-by-step explanation:

C(x)     Total cost in producing  x units

C- = C(x) /x   Average cost of producing x units    x > 0

Cannon Precision Instrument

C (x)   Total monthly cost for producing x units of M1 cameras

is    C(x)  =  0.0025x²  + 80x  +  10000

Then average cost of producing x cameras M1 is

C-(x)  =  ( 0.0025x²  + 80x  +  10000)  /x

C-(x)  =   0.0025x  + 80  + 10000/x

Taking derivatives on both sides of the equation

C-´(x)   =  0.0025   -  10000/x²

Then

C-´(x)   = 0

( 0.0025x² - 10000 ) / x²   =  0

0.0025x² - 10000 =  0

x²  =  10000 /0.0025         x²  = 4000000

x  =  2000 cameras
