I recently came across this question.I wanted to ask how do i solve this.I am new to references. Write a function, compute_bonuses() to calculate employee bonuses. Employee sales data are stored like this: 
$emp_data = { "bob" => { salary => 38.7, # in k$/yr sales => 23, # uni
+ts }, "jane" => { salary => 50.3, sales => 36, }, ... };

Employees get a 20% bonus on their base salary if their sales exceed 30 units. Your compute_bonuses() function should take a single argument like $emp_data above, and return a hashref with names as keys and bonus amounts as values. The output hashref only contains employees receiving a bonus, e.g. { "jane" => 10.06, ... }
