Answer:
108.505
Step-by-step explanation:
Let's talk money for just a second. Which would you rather have 20 dollars or 20.32 20dollars and 32 cents?
Isn't 20.32 bigger than 20.
You should say yes.
If that is true, then 108.505 should be larger than 108.5 not by much, but still larger.
Answer:
The system of equations is :
Equation 1- ![5x+2y=50](https://tex.z-dn.net/?f=5x%2B2y%3D50)
Equation 2- ![x+2y=30](https://tex.z-dn.net/?f=x%2B2y%3D30)
Number of vinyl doghouse = 5
Number of treated lumber doghouse =12.5
Step-by-step explanation:
Let x be the number of vinyl doghouses
y be the number of treated lumber doghouses
→If it takes the company 5 hours to build a vinyl doghouses and 2 hours to build a treated lumber doghouse. The company dedicates 50 hours every week towards assembling and painting doghouses.
Equation 1- ![5x+2y=50](https://tex.z-dn.net/?f=5x%2B2y%3D50)
→It takes an additional hour to paint each vinyl doghouse and an additional 2 hours to assemble each treated lumber doghouse. The company dedicates 30 hours every week towards assembling and paining dog houses.
Equation 2- ![x+2y=30](https://tex.z-dn.net/?f=x%2B2y%3D30)
→When we solve these equation we get the number of vinyl doghouse and treated lumber doghouse.
Subtract equation 2 from equation 1
![5x+2y-x-2y=50-30](https://tex.z-dn.net/?f=5x%2B2y-x-2y%3D50-30)
![4x=20](https://tex.z-dn.net/?f=4x%3D20)
![x=\frac{20}{4}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B20%7D%7B4%7D)
![x=5](https://tex.z-dn.net/?f=x%3D5)
Put value of x in equation 2
![x+2y=30](https://tex.z-dn.net/?f=x%2B2y%3D30)
![5+2y=30](https://tex.z-dn.net/?f=5%2B2y%3D30)
![2y=25](https://tex.z-dn.net/?f=2y%3D25)
![y=\frac{25}{2}](https://tex.z-dn.net/?f=y%3D%5Cfrac%7B25%7D%7B2%7D)
![y=12.5](https://tex.z-dn.net/?f=y%3D12.5)
Therefore, number of vinyl doghouse = 5, number of treated lumber doghouse =12.5
