Answer:
The expression for the combined areas of the window will be
(2x3^2x30) + 2x4^2x33
The total cost for the builder is $1596
Step-by-step explanation:
Cost of a window = area of window in square feet x price per square foot.
So, using this, we can find cost of n number of windows.
The cost of two rose windows is 2 x 3^2 x 30
The cost of two tulip windows is 2 x 4^2 x 33
The total cost is ( 2 x 3^2 x 30 ) + ( 2 x 4^2 x 33 )
By using the order of operations,
(2 x 3^2 x 30) + (2 x 4^2 x 33)
= ( 2 x 9 x 30 ) + ( 2 x 16 x 33 )
= (18 x 30 ) + (32 x 33)
= 1596
