Its B. 2/13, becouse you do the math correctly and you will find it eventually
There are 6 10 minute segments in an hour ( 60 / 10 = 6)
80 * 6 = 480 T-shirts in 1 hour
You should first of all distribute and combine like terms on both sides. You should subtract 6x from both sides. Once you have done that, you should add 80 to both sides and divide by 6 to get your answer as a simplified fraction of x=-2/3. The correct answer is b.
