Sagot :

Step 1

Find the number of windows on each floor

In a large building, there are 10 floors, each floor has the following;

[tex]\begin{gathered} 8\text{ windows }in\text{ the front} \\ 8\text{ windows in the back} \\ 4\text{ windows on the side to the right} \\ \text{and} \\ 4\text{ windows to the side on the left} \\ \text{Therefore, each floor has 24 windows} \end{gathered}[/tex]

Step 2

Find the number of windows in a large building

[tex]\begin{gathered} \text{There are 10 floors,} \\ \text{Number of windows in each large building = 10 }\times24\text{ = 240 windows} \end{gathered}[/tex]

Step 3

Find the cost the cleaning contractor will take to clean the windows in each building.

[tex]\text{\$}6\text{ }\times240\text{ = \$}1440[/tex]

Step 4

Find the cost of cleaning all the windows in 22 large buildings

[tex]22\times\text{ \$}1440=\text{ \$}31,680[/tex]

Hence, the cost of washing all windows in the 22 large buildings = $31,680
