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? The window's length is ___ feet.

length of window = 3/5 ft

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 =   (∵ 1 inch =  1/12 feet)

d.) yes, because the volume of the cone is greater than the volume of the sphere
