-1/5
Step-by-step explanation:
42x=7[x-1]
42x=7x-7
42x-7x=-7
35x=-7
x=-1/5
The computation shows that the total amount or cost raised will be $250.
<h3>How to calculate the cost?</h3>
From the information given, it was stated that the skating club collected $8 from each of the nine members and had already raised $178.
Therefore, the total amount will be;
= $178 + ($8 × 9)
= $178 + $72
= $250
Therefore, the total amount raised will be $250.

Answer: D) 5/2</h3>
==================================================
Explanation:
The parabola is symmetric around its vertex. This means that the roots are the same horizontal distance away from the vertex. Furthermore, we can apply the midpoint formula on the given roots to find the x coordinate of the vertex.
Find the midpoint of 2 and 3 to get (2+3)/2 = 5/2
Note: 5/2 = 2.5
