Answer:
5 shirts
Step-by-step explanation:
We can write the costs of both companies being equal as [tex]50 + 4s = 25 + 9s[/tex], where s = shirts.
Now, we solve this equation algebraically to find the # of shirts to break even.
Step 1: Subtract 4s from both sides.
Step 2: Subtract 25 from both sides.
Step 3: Divide both sides by 5.
Step 4: Check if solution is correct.
Therefore, the answer is 5 shirts.
