How to display optional attribute value in wordpress woocomerce?

Question

WordPress

<?php
global $product;
$attributes = $product->get_attributes();
foreach ( $attributes as $attribute ){
     $name = wc_attribute_label( $attribute['name'] );
     if ($name != 'Region' && $name != 'Fraction' && $name != 'BoostRating' && $name != 'BoostType1') {
        echo "<div class='attributerow radio_wrap'><div class='attributerowname _hidden'>" .  $name . "</div>";
        if ( $attribute['is_taxonomy'] ) {
            $values = wc_get_product_terms( $product->id, $attribute['name'], array( 'fields' => 'names' ) );
            echo apply_filters( 'woocommerce_attribute', wptexturize( implode( ', ', $values ) ), $attribute, $values );
        } else {
          $values = array_map( 'trim', explode( WC_DELIMITER, $attribute['value'] ) );
          echo apply_filters( 'woocommerce_attribute', wptexturize( '<div class="radio_line"><p class="radio_block radio"><a href="javascript:void(0)"></a><input type="radio" name="radio"><span class="atname">
                '.implode( '</p></div><div class="radio_line"><p class="radio_block radio"><a href="javascript:void(0)"></a><input type="radio" name="radio"><span class="atprice">11</span><span class="atname">', $values ) . '</span></p></div></div>' ), $attribute, $values );
        }
     }
}
?>

This code displays the name "name" of the product attributes.
But each product has its own price tag, how to display it?
Thank you!
