A bag contains 21 coins consisting of nickels and dimes. The total value of the coins is $1.45. Which system of equations can be used to determine the number of nickels,  $n,$  and the number of dimes,  $d,$  in the bag?

•  $0.10d+0.05n=21$  
   $n+d=1.45$  
  

•  $0.05n+0.10d=21$  
   $n+d=1.45$  
  

•  $0.10n+0.05d=1.45$  
   $n+d=21$  
  

•  $0.05n+0.10d=1.45$  
   $n+d=21$
