Problem: the grade point average of the entire class is 88 . if the average of one third of the class is 94 , what is the average of the rest of the class ?
Rationale: "let x be the number of students in the class . let p be the average of the rest of the class . 88 x = ( 1 / 3 ) 94 x + ( 2 / 3 ) ( p ) x 264 = 94 + 2 p 2 p = 170 p = 85 . the answer is d ."
annotated_formula: divide(subtract(multiply(88, const_4), 94), subtract(const_4, const_1))
