Diana decided she needed some new friends to play with. She understood that fish were not fun to hang out with, so she bought 3

baby mice and 2 baby pythons for a total cost of $103.50. Mr. Reyes also thought this was a great idea. He bought 3 baby mice and 3 baby pythons for a price of $148.50. Find the price of the mouse and the price of the python.

Answer:

Baby python: $45

Baby mouse: $4.5

Step-by-step explanation:

First of all, 3 baby mice and 2 baby pythons cost $103.50. When Mr. Reyes adds a baby python (He bought 3 baby mice and 3 baby pythons for a price of $148.50.) To find the price of a baby snake, you need to subtract both prices. 148.5-103.5=45, so a baby snake costs $45. Now we need to find the price of the baby mice, so we need to remove the snakes. 45*2=90. (2 snakes). 103.5-90=13.5, and 13.5/3=4.5, so a baby mouse costs $4.5.

Thanks

Step-by-step explanation:

Let m be the price of 1 baby mice

Let p be the price of 1 baby python

Given,

3m + 2p = 103.50

as equation 1.

and

3m + 3p = 148.50

as equation 2

From here we can easily use elimination method

for solving simultaneous equations.

Use Equation 1 - equation 2 to eliminate m to find p.

(3m - 3m) + (2p - 3p) = 103.50 - 148.50 \\  - p =  - 45 \\ p = 45

Substitute p into equation 1.

3m + 2(45) = 103.50 \\ 3m + 90 = 103.50 \\ 3m = 103.50 - 90 \\ 3m = 13.50 \\ m = 13.50 \div 3 \\  = 4.50

therefore 1 baby mice cost $4.50 and 1 baby python costs $45.

As a financial consultant, the CFO of a major television company has shared the profit function P(x) = −x4 - 2x3 + 21x2 + 22x −
drek231 [11]

Answer:

The company will break even at x=1 and x=4.

Step-by-step explanation:

The given profit function is

P(x)=-x^4-2x^3+21x^2+22x-40

Where, x is number of commercials.

Use synthetic division or long division to find the factors of the function.

P(x)=(x-1)(x^3+3x^2-18x-40)

P(x)=(x-1)(x+2)(x^2+x-20)

P(x) = -(x - 4) (x - 1) (x + 2) (x + 5)

Equate P(x)=0, to find the break even points.

-(x - 4) (x - 1) (x + 2) (x + 5)=0

Use zero product property and equate each factor equal to zero.

x=4,1,-2,-5

Therefore the zeros of the function P(x) are 4, 1, -2 and -5. Since x is number of commercials, therefore the value of x must be positive. Therefore the company will break even at x=1 and x=4.

The higher degree of the function is even and the leading coefficient is negative. So,

P(x)\rightarrow -\infty \text{ as }x\rightarrow \infty

P(x)\rightarrow -\infty \text{ as }x\rightarrow -\infty

Since the value of x must be positive, therefore the left end point is y-intercept of the graph, i.e., (0,-40).

Therefore the company faces huge loss when the number of commercials increases unboundly.

The graph of the function is given below.
