the grade point average of the entire class is 85 . if the average of one third of the class is 97 , what is the average of the rest of the class ?
"let x be the number of students in the class . let p be the average of the rest of the class . 85 x = ( 1 / 3 ) 97 x + ( 2 / 3 ) ( p ) x 255 = 97 + 2 p 2 p = 158 p = 79 . the answer is d ."
divide(subtract(multiply(85, const_4), 97), subtract(const_4, const_1))
