A full bucket of water weighs 3.4 kilograms (kg). After drinking 1/5 of the water, the bucket was re-weighed and the weight was 2.98 kilograms (kg). How many kilograms (kg) does the empty bucket weigh?
3.4 3.4 2.98 [OP_SUB] 1/5 [OP_DIV] [OP_SUB]
var_a = 3.4
var_b = 3.4
var_c = 2.98
var_d = var_b - var_c
var_e = 0.2
var_f = var_d / var_e
var_g = var_a - var_f
print('{:.2f}'.format(round(var_g+1e-10,2)))
