Question

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

Answer 1

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.

Answer 2

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.
