Unit rate= $$/lbs.
2.40/12=0.2
Your unit rate is $0.20
The expression we have is:
![2xy\cdot xy^2](https://tex.z-dn.net/?f=2xy%5Ccdot%20xy%5E2)
And we are given some values for x and y:
![\begin{gathered} x=2 \\ y=4 \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20x%3D2%20%5C%5C%20y%3D4%20%5Cend%7Bgathered%7D)
The first step will be to substitute the given values into the expression:
![2(2)(4)\cdot(2)(4)^2](https://tex.z-dn.net/?f=2%282%29%284%29%5Ccdot%282%29%284%29%5E2)
The next step is to solve 4^2 which is equal to 16:
![2(2)(4)\cdot(2)(16)](https://tex.z-dn.net/?f=2%282%29%284%29%5Ccdot%282%29%2816%29)
And then we solve the multiplications, 2(2)(4) is equal to 16 and (2)(16) is equal to 32:
![16\cdot32](https://tex.z-dn.net/?f=16%5Ccdot32)
Solving this final multiplication we get the result:
![512](https://tex.z-dn.net/?f=512)
