Answer:
![W = 16](https://tex.z-dn.net/?f=W%20%3D%2016)
![T = 67](https://tex.z-dn.net/?f=T%20%3D%2067)
Step-by-step explanation:
Represent trees with T and wreaths with W
Given
![T = 3 + 4 * W](https://tex.z-dn.net/?f=T%20%3D%203%20%2B%204%20%2A%20W)
![2 * W + T = 99](https://tex.z-dn.net/?f=2%20%2A%20W%20%2B%20T%20%3D%2099)
Solving (a): Cost of W
Substitute 3 + 4 * W for T in the second equation
![2*W + 3 + 4 * W = 99](https://tex.z-dn.net/?f=2%2AW%20%2B%203%20%2B%204%20%2A%20W%20%3D%2099)
![2W + 3 + 4 W = 99](https://tex.z-dn.net/?f=2W%20%2B%203%20%2B%204%20W%20%3D%2099)

![2W + 4 W = 99 - 3](https://tex.z-dn.net/?f=2W%20%2B%204%20W%20%3D%2099%20-%203)
![6W = 96](https://tex.z-dn.net/?f=6W%20%3D%2096)
Divide through by 6
![W =\frac{96}{6}](https://tex.z-dn.net/?f=W%20%3D%5Cfrac%7B96%7D%7B6%7D)
![W = 16](https://tex.z-dn.net/?f=W%20%3D%2016)
Hence, each wreath costs $16
Solving (b): Cost of T
![T = 3 + 4 * W](https://tex.z-dn.net/?f=T%20%3D%203%20%2B%204%20%2A%20W)
Substitute 16 for W
![T = 3 + 4 * 16](https://tex.z-dn.net/?f=T%20%3D%203%20%2B%204%20%2A%2016)
![T = 3 + 64](https://tex.z-dn.net/?f=T%20%3D%203%20%2B%2064)
![T = 67](https://tex.z-dn.net/?f=T%20%3D%2067)
Hence, each tree costs $67
The correct answer is (-2,1,2,8)
The range are the y- values
The explanation:
The range is the set of all second elements of ordered pairs (y-coordinates). Only the elements "used" by the relation or function constitute the range.
