Answer:
The total cost for each health club will be the same after 4 months.
Step-by-step explanation:
- Let A = membership fee for studio A
- B = membership fee for studio B
We want to when the total cost at each health studio is the same.
In other words, when A = B.
Therefore, the expression becomes


Step 1: Simplify both sides of the equation.

Step 2: Subtract 18.25x from both sides.


Step 3: Subtract 22 from both sides.


Step 4: Divide both sides by 6.25


Therefore, the total cost for each health club will be the same after 4 months.
Sales above monthly quota = 23800 - 17000 = $6800
So her commission = 0.05 * 6,800 = $340
Therefore her total salary for the month = 3600 + 340
= $3,940 (answer).
