Step-by-step explanation:
Answer:
I know the surface area is 120... don't know about volume
so, the repairman charges $45 for each hour of work, and $44 for the parts, now the parts are obtained only once, so that's a one-time charge of 44 bucks, let's see how the hours go.
1 hour of work................... 45 + 44(1)
2 hours of work................45 + 44(2)
3 hours of work................45 + 44(3)
4 hours of work................45 + 44(4)
x hours of work................45 + 44(x)
so the cost equation, with x = hours, C(x) = 45 + 44x.
what is x if C(x) = 179?
![\bf \stackrel{C(x)}{179}=44+45x\implies 135=45x\implies \cfrac{135}{45}=x\implies 3=x](https://tex.z-dn.net/?f=%5Cbf%20%5Cstackrel%7BC%28x%29%7D%7B179%7D%3D44%2B45x%5Cimplies%20135%3D45x%5Cimplies%20%5Ccfrac%7B135%7D%7B45%7D%3Dx%5Cimplies%203%3Dx)
