Task 4

1. This code is working perfectly but it's hard to maintain, please make the code below cleaner and readable

public function getPrice() {
  if($customer->group == 'distributor') {
    if($customer->status == 'active') {
      if($customer->debt > 10000000) {
        return error('this customer cannot make a purchase due to his debt over limit');
      } else {
        return Price::get('distributor');
      }
    } else {
      return error('this customer is not active')
    }
  } elseif($customer->group == 'general') {
    if($customer->status == 'active') {
      if($customer->debt > 10000000) {
        return error('this customer cannot make a purchase due to his debt over limit');
      } else {
        return Price::get('general');
      }
    } else {
      return error('this customer is not active')
    }
  }
}
