P=2l+2w\\
l=2\text{ m }10\text{ cm}=210 \text{ cm}\\
w=45\text{ cm}\\\\
P=2\cdot210+2\cdot45\\
P=420+90\\
P=510 \text{ cm}

elena-14-01-66 [18.8K]

Answer:

6.84 ≤ x ≤ 37.39

Step-by-step explanation:

we have

P(x)=-0.5x^2+23x+92 -----> equation A

we know that

The company wants to keep its profits at or above $225,000,

so

PXx)\geq 225 -----> inequality B

Remember that P(x) is in thousands of dollars

Solve the system by graphing

using a graphing tool

The solution is the interval [6.78,39.22]

see the attached figure

therefore

A reasonable constraint for the model is

6.84 ≤ x ≤ 37.39
