It wants to know how much one tshirt is. Susan did the problem wrong, they want to know if know how to do it right. She should have divided $12.75 by 3 not subtracted $2. :) I hope this helps :)
Answer:
center = (-2, 3)
radius = 2
Step-by-step explanation:
(x+2)^2 + (y-3)^2 = 4
Use the formula: (x - h)^2 + (y - k)^2 = r^2
where (h, k) = center, radius = r

...
(x - (-2))^2 + (y - 3)^2 = 4 = (2)^2
center = (-2, 3)
radius = 2

A is the correct answer</span>
X would equal 4
set AB=AC
18=3x+6
minus 6 on both sides
12=3x
divide both sides by 3
x=4
