Sholpan [36]

Answer:

C. $-0.00005d^2+11.8d-9000$

Step-by-step explanation:

Given:

Cost Price for producing 'd' dog lashes = $9000+3.2d$

Revenue Generated from selling 'd' dog lashes = $d(15-0.00005d)$

We need to find the profit earned from producing and selling 'd' dog lashes.

Solution:

Now we know that;

profit earned from producing and selling 'd' dog lashes can be calculated by Subtracting Cost Price for producing 'd' dog lashes from Revenue Generated from selling 'd' dog lashes.

framing in equation form we get;

Profit earned = $d(15-0.00005d)-(9000+3.2d)$

Now Applying Distributive property we get;

Profit earned = $15d-0.00005d^2-9000-3.2d$

Now Combining like terms we get;

Profit earned = $-0.00005d^2+15d-3.2d-9000$

Profit earned = $-0.00005d^2+11.8d-9000$

Hence Profit earned from producing and selling 'd' dog lashes is $-0.00005d^2+11.8d-9000$ .

HELP ILY A tree is 4 1/2 feet tall. It is expected to grow by 1 3/4

ANEK [815]

Answer:

It will take 21 years.

Step-by-step explanation:

First, find what x would be for it to equal 40 feet. This can be done with the equation 4.5 + 1.75x = 40.

4.5 + 1.75x = 40

Subtract 4.5 from both sides. This cancels out the +4.5.

1.75x = 40 - 4.5

Subtract 4.5 from 40 to get 35.5.

1.75x = 35.5

Divide both sides by 1.75. This cancels out the *1.75.

x = 35.5/1.75

Expand 35.5/1.75 by multiply both the numerator and denominator by 100.

x = 3550/175

Reduce 3550/175 by canceling out 25.

x = 142/7 = 20 2/7

Go up by one from 20 to get the answer of 21 years.
