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
