Question 672298
The correct answer is {{{B}}}.
The total number of books available is {{{(30-3)+(30-5)}}}, or {{{27+25}}},which is {{{52}}}. To find the class periods for which there are {{{not}}} enough books, find the total number of books needed for {{{each}}}{{{ period}}}, as given in the table below.

PERIOD------------------ {{{1}}} --------{{{2}}}----{{{ 3}}}---- {{{4}}}----- {{{5 }}} 
BOOKS NEEDED--------- {{{23}}}------ {{{49}}}---{{{ 56}}}--- {{{50}}}----{{{ 27}}}

The {{{only}}} entry in the table with {{{more}}} than{{{ 52}}} is {{{56}}} for period {{{3}}}. If you selected answer choice {{{E}}}, you probably used {{{60}}} as the number of {{{available}}} books and {{{did}}}{{{ not}}}{{{ take}}}{{{ into}}} {{{account}}} the {{{8}}}{{{ missing}}}{{{ books}}}.
