the grade point average of the entire class is 87 . if the average of one third of the class is 95 , 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 . 87 x = ( 1 / 3 ) 95 x + ( 2 / 3 ) ( p ) x 261 = 95 + 2 p 2 p = 166 p = 83 . the answer is c ."
divide(subtract(multiply(87, const_4), 95), subtract(const_4, const_1))
