Josh spends a total of $5.50 buying N items in the convenience store. If each of the items is either a 5 cents single bubblegum, or a 50 cents bubblegum pack, then N may be which of the following?  Choices.
A) 99 B) 100 C) 101 D) 109 E) 140
Let x be the number of single bubblegums and y be the number of bubblegum pack.   then   5x+50y=550   or x+10y=110   or x=110-10y   Now,   let y=0, then x= 110 and N=x+y or N=0+110=

110.   let y=1, then x=100 and N=100+1= 
<gadget id="calculator">100+1</gadget>
<output>101</output>
101 (given in the options)   let y=2, then x= 90 and N=92   the value will further decrease and hence we do not need to calculate anymore values.   ANSWER:- 101
