Final answer:

By substituting the side length of 3 feet into the formula c = 25s^2, we find that Ricardo will pay $225 for the square sheet of glass.

Step-by-step explanation:

To find the cost c of a square sheet of glass using the formula c = 25s^2, where s represents the length of a side in feet, we substitute the given side length of 3 feet into the formula:

  • s = 3 feet
  • c = 25 × (3 feet)^2
  • c = 25 × 9 square feet
  • c = 225 dollars

Therefore, Ricardo will pay $225 for a square sheet of glass that is 3 feet on each side.

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.
