Given that a pencil case with 14 identical pencils weighs 11.14 kilograms (kg). When the empty pencil case weighs 0.5 kilograms (kg), how many kilograms (kg) does one pencil weigh?
11.14 0.5 [OP_SUB] 14 [OP_DIV]
var_a = 11.14
var_b = 0.5
var_c = var_a - var_b
var_d = 14
var_e = var_c / var_d
print('{:.2f}'.format(round(var_e+1e-10,2)))
