You're welcome.
To find the cost of the glass to cover the picture, you need to calculate the area of the rectangular picture frame first.
The area of a rectangle is calculated by multiplying its length by its width. In this case, the length is 4.0 inches and the width is 5.5 inches. Therefore, the area of the picture frame is:
Area = Length * Width = 4.0 inches * 5.5 inches = 22.0 square inches.
Now, to find the cost of the glass per square inch, we are given that it is $0.99. So, to calculate the cost of the glass to cover the picture, you need to multiply the area of the picture frame by the cost per square inch:
Cost of glass = Area * Cost per square inch = 22.0 square inches * $0.99 per square inch = $21.78.
So your answer of $21.78 is correct. The cost of the glass to cover the picture is indeed $21.78.
