W + y = 30w = 30 - y
11.95w + 12.50y = 364.55

11.95(30 - y) + 12.50y = 364.55
358.50 - 11.95y + 12.50y = 364.55
-11.95y + 12.50y = 364.55 - 358.50
0.55y = 6.05
y = 6.05 / 0.55
y = 11 <=== there were 11 yellow sweatshirts sold

w + y = 30
w + 11 = 30
w = 30 - 11
w = 19 <=== there were 19 white sweatshirts sold
