Woojin's family harvested potatoes in the field. The younger brother dug out 3.8 kilograms (kg), and the older sister dug out 8.4 kilograms (kg) more than the younger brother did. If Woojin dug out 3720 grams (g) more than 1/10 of the weight of her sister did, how many kilograms (kg) of Woojin's harvested potatoes?
3.8 8.4 [OP_ADD] 1/10 [OP_MUL] 3720 1000 [OP_DIV] [OP_ADD]
var_a = 3.8
var_b = 8.4
var_c = var_a + var_b
var_d = 0.1
var_e = var_c * var_d
var_f = 3720
var_g = 1000
var_h = var_f / var_g
var_i = var_e + var_h
print('{:.2f}'.format(round(var_i+1e-10,2)))
