Hint:For Velma to learn the least number of characters on Saturday, she needs to learn the maximum number on the rest of the days. Make a table of days and fill with characters learned each day to avoid any confusion.Sun = 12Mon = 12Tue = 12Wed = 12Thu = 12Fri = 4Sat = ?Total = 71Now, try to solve yourself before looking at the complete solution.Complete step-by-step solution:Total number of characters to be learned = 71Let the number of characters leaned by Velma on Saturday be x.Number of characters learned on Friday = 4Number of characters learned on any other day = 12 (a dozen)Total number of such days where Velma learns 12 characters = 5The sum of characters learned on each day should be equal to 71Which mean that 12+12+12+12+12+4+x = 71=> 64+x=71=> x = 71-64 = 7.Hence, Velma needs to learn at least 7 Japanese hiragana characters on Saturday. Option (C)NOTE:1) 1 Dozen = 12 items2) The most common mistake that one can make here is to forget Sunday. In that case you come up with the answer 19.
