Starting in March, Yoona decided to donate 20,000 won per month to an international child support organization. How much did Yoona donate until August?
20000 8 3 [OP_SUB] 1 [OP_ADD] [OP_MUL]
var_a = 20000
var_b = 8
var_c = 3
var_d = var_b - var_c
var_e = 1
var_f = var_d + var_e
var_g = var_a * var_f
print(int(var_g))
