A full bottle of milk weighs 1650 grams (g). After drinking 1/3 of the milk, I weighed the bottle again, which was 1250 grams (g). How many grams (g) does the bottle alone weigh?
1650 1650 1250 [OP_SUB] 1 [OP_MUL] 1/3 [OP_DIV] [OP_SUB]
var_a = 1650
var_b = 1650
var_c = 1250
var_d = var_b - var_c
var_e = 1
var_f = var_d * var_e
var_g = 0.3333333333333333
var_h = var_f / var_g
var_i = var_a - var_h
print(int(var_i))
