Area to cover= 1200 ft^2
Boxes= 22.69 ft^2
Part 1.
The number of boxes she has to purchase is given by the following equation.
[tex]22.69*x=1200[/tex]
Where x is the number of boxes.
Solving for x:
[tex]x=\frac{1200}{22.69}=52.886\approx53[/tex]As the number of boxes has to be a integer the number will be: 53.
Part 2.
The total square feet for 53 boxes is going to be:
[tex]22.69ft^2*53=1202.57ft^2\approx1202.6ft^2[/tex]The total square feet for 53 boxes is 1202.6 square feet.
Part 3.
each box= $55.60
The cost for 53 boxes is:
[tex]55.60*53=2946.8[/tex]The total cost is: $2946.8
Part 4:
Labor cost per square feet=0.99
Total square feet to cover= 1200.
The total cost will be:
[tex]0.99*1200=1188[/tex]The total labor cost is: $1188.
