Yesterday, Eunji's uncle gave Eunji some pocket money. Eunji bought a notebook with half of her pocket money, and when she received an additional 550 won from her mother today, her money became 1,000 won. How much money did she get from her uncle?
1000 550 [OP_SUB] 2 [OP_MUL]
var_a = 1000
var_b = 550
var_c = var_a - var_b
var_d = 2
var_e = var_c * var_d
print(int(var_e))
