Percentage of black T-shirt sold = 320/400 x 100 = 80%
Percentage of blue T-shirt sold = 270/300 x 100 = 90%
Answer: There is a greater percentage of Blue T-Shirt sold.
Answer:
B
Step-by-step explanation:
1. A reflection across the origin has a rule

2. A translation 9 units to the left and 7 units down has a rule

Then the rule for a reflection across the origin followed by a translation 9 units to the left and 7 units down is

This means that the point with coordinates (x,y) has the image with coordinates (x',y')=(-x-9,-y-7).
We get all these to have the same denominators for all the fractions.
2*2/9*2 = 4/18
1*2/9*2 = 2/18
1*3/6*3 = 3/18
Now we can add all the numerators.
4/18 + 2/18 + 3/18 = 9/18
Simplify our answer by dividing both numbers by 3, then by 2.
9/3 and 18/3 = 3/6= 1/2
Our final answer is 1/2
