You are a contractor who is installing new windows. You are working on a house that has 6 windows that are each 3 feet by 4 feet.If the glass for the windows costs $0.05 per square inch, approximately how much money will the glass cost for all of the window installations?

A.
$36
B.
$43
C.
$432
D.
$518

Answers

Answer:

D. $518

Step-by-step explanation:

We know that the windows are 3ft by 4ft, find the area:

A = L * W

A = 3ft * 4ft

A = 12 sq ft

12 sq ft is the area of each window in the house

Now multiply the amount of windows in the house by the 12 sqft:

12 sqft * 6

72 sq ft

The combined area of all 6 windows are 72 sqft. Now since 1 sqft is equal to 144 sq inches, simply convert the square feet into squared inches:

72 * 144

10,368 squared inches

Since each square inch costs 0.05 cents, multiply the amount of square inches by the cost of each square inch:

0.05 * 10,368

$518.4

Since D. is the closest value, that would be our answer.

put data into calc should get
A = 1000 and B = 1.06
y=1000(1.06^x)

x=30 years, y=1000(1.06^30)=5743

A=1000 is the principal (initial deposit)
B=1.06 mean compound interest 6%

Solve the system using elimination.

5x + 8y = –29
7x – 2y = –67

Answers

7x-2y+-67
multiply both sides of the bottom by 4 and add                                            5x+8y=-29 
 28x-8y=268
 
  33x=-297
   x=-9 


5(-9) +8y= -29 
-45 +8y =-29 
8y= 16 
y=2
