Awindow is being replaced with tinted glass. the plan below shows the design of the window. each unit length represents 1 foot. the glass costs $23 per square foot. how much will it cost to replace the glass? use 3.14 for π.

Let us solve for the total area. In this problem, we solve area 1 (the rectangle in the middle) and the area 2 ( the two half circle on the sides).

Solve for area 1:
Area rec = L * W = 5units * 4 units = 20 squared units

Solve for area 2:
Area cir = pi *r² = 3.14 * (2 units)² = 12.56 squared units

Total area = 20 + 12.56 = 32.56 foot²
Total cost = 32.56 foot² * ($23/foot²) = $ 748.88

Total cost is $748.88.

C. i believe it is (5×(-20))+(100×(0.7))
