First we already know that he makes 200 dollars a month at the bowling alley so we can do 500-200 and he would need to 300 dollars from delivering newspapers. Then we need to divide 300 by 5 to see how many hours he needs to work and we would get 60. That means the answer is he would have to deliver newspapers for 60 hours
Answer:

Answer:
![9.42\ ft^{2}](https://tex.z-dn.net/?f=9.42%5C%20ft%5E%7B2%7D)
Step-by-step explanation:
step 1
Find the surface area of one hanging lantern
we know that
The surface area of a cone (hanging lantern) is equal to
![SA=\pi r^{2} +\pi rl](https://tex.z-dn.net/?f=SA%3D%5Cpi%20r%5E%7B2%7D%20%2B%5Cpi%20rl)
we have
![r=0.5\ ft](https://tex.z-dn.net/?f=r%3D0.5%5C%20ft)
![l=1.5\ ft](https://tex.z-dn.net/?f=l%3D1.5%5C%20ft)
assume
![\pi=3.14](https://tex.z-dn.net/?f=%5Cpi%3D3.14)
substitute the values
![SA=(3.14)(0.5)^{2} +(3.14)(0.5)(1.5)](https://tex.z-dn.net/?f=SA%3D%283.14%29%280.5%29%5E%7B2%7D%20%2B%283.14%29%280.5%29%281.5%29)
![SA=3.14\ ft^{2}](https://tex.z-dn.net/?f=SA%3D3.14%5C%20ft%5E%7B2%7D)
step 2
Find the surface area of the three hanging lanterns
![SA=(3)*3.14=9.42\ ft^{2}](https://tex.z-dn.net/?f=SA%3D%283%29%2A3.14%3D9.42%5C%20ft%5E%7B2%7D)
