The cost C (in dollars) of making a square window with a side length of n inches is represented by C=n^2/5+175. A window costs $355. What is the side length (in feet) of the window?

#1**+1 **

355 = n^{2/5} + 175

n^{2/5 }= 180

n = 434691.61 in = 36224 feet .... a very LARGE window ! ( are you sure you copied the equation correctly?)

Perhaps you meant n^{2 }/ 5 + 175 then n = 30 inches = 2.5 feet
