所以我不完全确定我错过了什么，但我似乎无法正确添加总价。不过，我可以得到每个单独的价格。

基本上这个想法是点击一个灰色的图像，它会生成一个列表（工作），它假设给出一个价格（确实如此），如果你点击另一个图像它应该更新价格，这将添加到以前价格。

有人可以告诉我我错过了什么或做错了什么吗？

您可以进行以下更改吗？

          var kbtotal = 0;//added
          var mstotal = 0;//added
          var keyboardPrice = 59;
          sum = keyboardPrice * 1.2;
          console.log(sum);
          kbtotal = sum / 40; // changed
          console.log(kbtotal); // changed

          var mousePrice = 59;
          sum = mousePrice * 1.2;
          console.log(sum);
          mstotal = sum / 40; // changed
          console.log(mstotal); // changed

          var finaltotal = parseFloat(kbtotal) + parseFloat(mstotal);
          $('#finaltotal').text(finaltotal); // added

<div id="summaryTotal">
    <p>Get this system for as little as: <div id="finaltotal"></div></p>
</div>
