Find the minimum cost of producing 60000 units of a product, where x is the number of units of labor, at $99 per unit, and y is

Y_Kistochka [10]

Answer:

The minimum cost of producing 60000 units of a product is $105867

Step-by-step explanation:

Since x is the number of units of labor, at $99 per unit, and y is the number of units of capital expended, at $84 per unit, The cost C(x,y) is given by:

$C(x, y) = 99x + 84y$

$P(x, y) = 100x^{0.25}y^{0.75}$

For the minimum cost:

$100x^{0.25}y^{0.75}=60000\\x^{0.25}(\frac{33x}{28} )^{0.75}=600\\x^{0.25}(\frac{33}{28} )^{0.75}x^{0.75}=600\\x^{0.25+0.75}*1.131=600$

Using the langrage multiplier,

$99=0.25(100)x^{-0.75}y^{0.75}\lambda...(1\\84=0.25(100)x^{0.25}y^{-0.25}\lambda...(2$

Dividing both equation 1 and 2

$y=\frac{33}{28}x$

Substituting $y=\frac{33}{28}x$ in $100x^{0.25}y^{0.75}=60000$ , we get:

$x_{min}=530.44$ labor units

Substituting $x_{min}=530.44$ labor units in $y=\frac{33}{28}x$ , we get

$y_{min}=\frac{33}{28}*530.44=625.16$ labor unit

$C(x, y) = 99x + 84y=99(530.44)+84(635.16) = $105867\\$

The minimum cost of producing 60000 units of a product is $105867

Clint is in study hall reading the hunger games after 20 minutes he is on page 151 after 45 minutes he's on page 181 how many pa

Mademuasel [1]

After 20 minutes Clint is on page = 151

After 45 minutes Clint is on page = 181

Time slot = $45-20=25$ minutes

Difference in pages in 25 minutes = $181-151=30$ pages.

Lets suppose Clint is reading each page at same pace.

So , In 25 minutes, he can read = 30 pages

In 1 minute he can read = $\frac{30}{25}=1.2$ pages

Initial time is 20 minutes, so he can read the number of pages in 20 minutes = $20\times1.2=24$

So, number of pages Clint read prior to study hall were =

$151-24=127$ pages.
