The formula to find the cost c of a square sheet of a glass is c=25s2 where a represents the length of a side in feet. how much will ricardo pay for a square sheet of glass that is 3 feet on each side

Respuesta :

To calculate the cost of Ricardo, we just have to substitute the measurement of the length he wants to the function of the cost given. We do as follows:

c = 25s^2
c = 25(3)^2
c = 225

Therefore, the cost would be 225. 

Hope this answers the question. Have a nice day.
