I spent 22,000 won on buying 15 apples that cost 1,000 won each and peaches that cost 2,000 won each. Find how many peaches were bought.
22000 1000 15 [OP_MUL] [OP_SUB] 2000 1000 [OP_SUB] [OP_DIV]
var_a = 22000
var_b = 1000
var_c = 15
var_d = var_b * var_c
var_e = var_a - var_d
var_f = 2000
var_g = 1000
var_h = var_f - var_g
var_i = var_e / var_h
print(int(var_i))
