Answer:
<h2>x = -7 or x = 1</h2>
Step-by-step explanation:

I would say pick the second diagram. And 25 hours.
Ratios shall be used
Selling 3x as many tie-dyed as silk is the equivalent of ratio 3:1 (Three tie dies for 1 silk)
Add up the total numbers in the ratio (By that I mean 3 + 1) to get 4
Divide the total number sold by 4 to get 42
Multiply 42 by 3 (The number of tie dyes sold in the ratio) to get 126
126 tie-dyed shirts were sold
A is 31,570 got it right on my test
