The cost C (in dollars) of making a square window with a side length of n inches is represented by C=n25+175. A window costs $355. What is the length (in feet) of the window?

Respuesta :

Answer:

Length of window = 3/5 feet

Step-by-step explanation:

Cost of making one window (C) = $ 355

Cost of making a square window with length n inch is C = n(25) + 175

C = 25n + 175

By substituting the value of C and n in above equation:

355 = 25n + 175

25n = 355 - 175

25n = 180

n = 180/25

n = 36/5

Length of a square window in inches = 36/5

Length of a square window in feet = [tex]\frac{36}{5} \times \frac{1}{12} = \frac{3}{5} feet[/tex]  (∵ 1 inch =  1/12 feet)

Answer:

This is the answer...

Step-by-step explanation:

These are the steps.

Since an expert answered I'll just give myself some free points.

I also think he means the 2 is an exponent.
