CNN 10: 《Changing The Travel Industry》

This tech. will add up to $305 billion of value to the travel industry by 2025, according to research by the world economic forum.

上面是CNN记者说的原话。

出现的结果是 $305 billion of value... 但是词典例句均显示这种of结构：the value of  $100 ,

所以，我的疑问是究竟是 $305 billion of value..还是应该是 the value of  $305 billion....呢？

即应该是This tech. will add up to the value of $305 billion to the travel industry...吗？
