+176 Antrope, Dornetic, and Glaivieur have sold a total of 237 candy bars. Glaivieur sold 30 more candy bars than Antrope. Dornetic sold 33 fewer candy bars than Antrope. How many candy bars did Dornetic sell?
+308 Answer: Dornetic sold 47 candy bars.
Solution:
Let A be the number of candy bars Antrope sold. Let D be the number of candy bars Dornetic. Let G be the number of candy bars Glaivieur has sold.
A + D + G = 237
G = A + 30
A = D + 33
Substition:
D + 33 + D + A + 30 = 237
3D + 96 = 237
3D = 141
D = 47
