Answer:
The answer is 15 Shirts
Step-by-step explanation:
We want to know what x is going to equal that makes the equation the same.
First, I make the euations equal to each other by substituting the y -->
7x + 50 = 10x + 5
Then, I combine my similar terms --> 45 = 3x
After that, I divide by 3 to get x on its own --> --> 15 = x
This means that after 15 Shirts are sold, the costs for both companies are the same.
