Currently, Minjoo's piggy bank has 12,000 won and Siwoo's piggy bank has 4,000 won. If Minjoo puts 300 won a day and Siwoo 500 won a day into their piggy banks tarting tomorrow, after how many days will the money in Minjoo's and Siwoo's piggy banks become the same?
12000 4000 [OP_SUB] 500 300 [OP_SUB] [OP_DIV]
var_a = 12000
var_b = 4000
var_c = var_a - var_b
var_d = 500
var_e = 300
var_f = var_d - var_e
var_g = var_c / var_f
print(int(var_g))
