Help with math earn 10 points
Luda [366]

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 --> \frac{45}{3} =\frac{3x}{3} --> 15 = x

This means that after 15 Shirts are sold, the costs for both companies are the same.
