It takes 0.84 meters (m) of shiny string to decorate one tree. If there are 50 centimeters (cm) of rope left after decorating 10 trees, how many meters (m) of rope were there before decorating the tree?
0.84 10 [OP_MUL] 50 100 [OP_DIV] [OP_ADD]
var_a = 0.84
var_b = 10
var_c = var_a * var_b
var_d = 50
var_e = 100
var_f = var_d / var_e
var_g = var_c + var_f
print('{:.2f}'.format(round(var_g+1e-10,2)))
