The clothing store sold 3/5 of the T-shirts that were left from yesterday's sale this morning. In the afternoon, we sold 180 T-shirts in total, including surplus T-shirts of this morning and new T-shirts. If the number of T-shirts sold in the morning is equal to the number of T-shirts sold in the afternoon, how many T-shirts were left after selling yesterday?
180 3/5 [OP_DIV]
var_a = 180
var_b = 0.6
var_c = var_a / var_b
