At a large market, in the morning, I sold 3/5 of the snacks that were displayed at dawn. In the afternoon, 180 snacks  in total were sold, including those left from the morning and newly displayed snacks. If the number of snacks sold in the morning and the snack sold in the afternoon was the same, how many snacks were displayed at dawn?
180 3/5 [OP_DIV]
var_a = 180
var_b = 0.6
var_c = var_a / var_b
print(int(var_c))
