问题如下：
4.Using the information in Exhibit 3 and Stanza's assumptions, total estimated revenue from consoles next year should be closest to:
选项：
A.$2,494 million.
B.$2,548 million.
C.$2,594 million.
解释：
4.C
Note: To forecast new sales after a 100% increase in sales, we would multiply old sales by (100% + 100%) = 2. Similarly, an increase of 375% means that old sales needs to be multiplied by (100% + 375%) = 4.75 (not 3.75) to forecast new sales.
这道题的100+375=475，没有理解，也没找到出处，能帮忙解答一下吗
