Answer:
--- (a)
---- (b)
Step-by-step explanation:
Given
Per ride (r) = $8
Per baseballs (s) = $6
Total = $100
Required
Represent using an equation
If 1 ride is $8.
r rides would be 8r
If 1 baseball is $6
s baseballs would be 6r.
So, total is:
![8r + 6s = 100](https://tex.z-dn.net/?f=8r%20%2B%206s%20%3D%20100)
Solving (b):
Value of s when r = 14
![8r + 6s = 100](https://tex.z-dn.net/?f=8r%20%2B%206s%20%3D%20100)
Substitute 14 for r
![8 * 14 + 6s = 100](https://tex.z-dn.net/?f=8%20%2A%2014%20%2B%206s%20%3D%20100)
![112+ 6s = 100](https://tex.z-dn.net/?f=112%2B%206s%20%3D%20100)
Solve for 6s
![6s = 100 - 112](https://tex.z-dn.net/?f=6s%20%3D%20100%20-%20112)
![6s = -12](https://tex.z-dn.net/?f=6s%20%3D%20-12)
Solve for s
![s = -12/6](https://tex.z-dn.net/?f=s%20%3D%20-12%2F6)
![s = -2](https://tex.z-dn.net/?f=s%20%3D%20-2)

Step-by-step explanation:
5x+8-x=3x+6
5x-x-3x=-8+6
4x-3x= -2
1x= -2
Therefore,LHS is not equal to RHS
