No. of rows returned and sum of row field

Hi

I need to know how may rows a given query returns and also I need to calculate the sum of a given field in a row. 

See below... thanks in advance

<?php session_start(); 
$session=session_id();

  // load records from 'basket'
  list($basketRecords, $basketMetaData) = getRecords(array(
    'tableName'   => 'basket',
    'loadUploads' => false,
    'allowSearch' => false,
    'where' => "session='$session'",
  ));
?>

<table>
<tr>
<td>Course</td><td>Price</td></tr>
<?php foreach ($basketRecords as $record): ?>
<tr>
<td><?php echo htmlencode($record['course']) ?></td><td><?php echo htmlencode($record['price']) ?></td>
</tr>
<?php endforeach ?>
</table>

<-- How can I calculate the number of rows returned? (i need this figure in order to calculate a discount) -->
<-- How can I get the sum total for the $record['price'] field of all returned rows? -->
