If you multiply the 9 in the 900 by 5 you get 45 which is 5% of 900, multiply that by 4 gives 180 so she should have $180
Answer:
The price per square foot is $0.50
Step-by-step explanation:
step 1
Find the area of the canvas
The area of the rectangular canvas is equal to
![A=LW](https://tex.z-dn.net/?f=A%3DLW)
we have
![L=4\frac{1}{2}\ ft= 4+\frac{1}{2}=\frac{4*2+1}{2}=\frac{9}{2}\ ft](https://tex.z-dn.net/?f=L%3D4%5Cfrac%7B1%7D%7B2%7D%5C%20ft%3D%204%2B%5Cfrac%7B1%7D%7B2%7D%3D%5Cfrac%7B4%2A2%2B1%7D%7B2%7D%3D%5Cfrac%7B9%7D%7B2%7D%5C%20ft)
![W=2\ ft](https://tex.z-dn.net/?f=W%3D2%5C%20ft)
substitute
![A=(\frac{9}{2})(2)=9\ ft^2](https://tex.z-dn.net/?f=A%3D%28%5Cfrac%7B9%7D%7B2%7D%29%282%29%3D9%5C%20ft%5E2)
step 2
Find the price per square foot
Divide the cost by the area
so
![\frac{4.50}{9}=\$0.50\ per\ square\ foot](https://tex.z-dn.net/?f=%5Cfrac%7B4.50%7D%7B9%7D%3D%5C%240.50%5C%20per%5C%20square%5C%20foot)
