---------------------------
t = (4/7)s
t + s = 440
------
Substitute for "s" and solve for "t":
------
t + (7/4)t = 440
(11/4)t = 440
(1/4)t = 40
t = 160 (iced tea has 160 calories)
---
s = 280 (Cobb salad has 280 calories)

Let +x+ = number of calories
in Cobb salad
+%284%2F7%29%2Ax+%2B+x+=+440+
+%2811%2F7%29%2Ax+=+440+
+x+=+%287%2F11%29%2A440+
+x+=+7%2A40+
+x+=+280+
+%284%2F7%29%2Ax+=+%284%2F7%29%2A280+
+4%2A40+=+160+
The iced tea has 160 calories
