How to add the word Discount before the percentage?

Question

Programming

Hey!
I'm going to add the word "Discount" to the products on WooCommerce before the percentage.
Who knows php well, tell me where in the code you need to add the word?
PHP code:

<?php elseif($product->is_on_sale() && $flatsome_opt['sale_bubble_percentage'] && $product->product_type == 'simple') : ?>
<div class="callout <?php echo $flatsome_opt['bubble_style']; ?>">
    <div class="inner">
      <div class="inner-text"><?php 
    	$price = '';
    $percentage = round( ( ( $product->regular_price - $product->sale_price ) / $product->regular_price ) * 100,0);
    echo '-'.$price . sprintf( __('%s', 'woocommerce' ), $percentage . '%' ); ?></div>
    </div>
</div><!-- end callout -->

Displayed code on the site:

<div class="callout style2">
    <div class="inner">
      <div class="inner-text">-7%</div>
    </div>
</div><!-- end callout -->
