Problem: if the average of w , b , c , 14 and 15 is 12 . what is the average value of w , b , c and 29
Rationale: w + b + c + 14 + 15 = 12 * 5 = 60 = > w + b + c = 60 - 29 = 31 w + b + c + 29 = 31 + 29 = 60 average = 60 / 4 = 15 answer d
annotated_formula: divide(add(subtract(subtract(multiply(add(const_1, const_4), 12), 15), 14), 29), const_4)
