A bucket full of water weighs 320 kilograms (kg). After using 1/2 of the water, the bucket weighs 175 kilograms (kg). What is the weight of the empty bucket in kilograms (kg)?
320 320 175 [OP_SUB] 2 [OP_MUL] [OP_SUB]
var_a = 320
var_b = 320
var_c = 175
var_d = var_b - var_c
var_e = 2
var_f = var_d * var_e
var_g = var_a - var_f
print(int(var_g))
