<h2>
Explanation:</h2>
The complete question is attached below. In order to solve this problem, we'll use a graphing tool. First of all, we'll say that the LHS is a linear function and the RHS is another linear function, so for each case, we'll have:

For each graph,
will be drawn in red while
will be drawn in blue.
Case 1:

So by equating both equations:

By using graphing tool we get a point of intersection at which the x-value is the solution to our equation. So:

Answer:
Tax: $3.06
Step-by-step explanation:
7% of 43.75 = 0.07 × 43.75 = 3.0625
43.75 increase 7% =
43.75 × (1 + 7%) = 43.75 × (1 + 0.07) = 46.8125
