42. For next year, the Chef’s Union has requested a 10 percent salary increase for each of its members, whereas the Hotel Managers’ Union has requested only an 8 percent salary increase for each of its members. These facts demonstrate that the average dollar amount of the raises that the Chefs’ Union has requested for next year is greater than that of the raises requested by the Hotel Managers’ Union .
Which one of the following, if true, most strengthens the argument?
A.The Chefs’ Union has many more members than does the Hotel Managers’ Union. B.The Chefs’ Union is a more powerful union than is the Hotel Managers’ Union and is therefore more likely to obtain the salary increases it requests C.The current salaries of the members of the Chefs’ Union are, on average, higher than the current salaries of the members of the Hotel Managers’ Union
D.The average dollar amount of the raises that the members of the Chefs’ Union received last ear was equal to the average dollar amount of the raises that the members of the Hotel Managers’ Union received E.The members of the Chefs’ Union received salary increases of 10 percent in each of the last two years, while the members of the Hotel Managers’ Union received salary increases of only 8 percent in each of the last two years
"the average dollar amount of the raises” 究竟是什么意思呢？化成数学式子又是怎么的呢？数学不好，没有思路，求大牛解释
