(a)
Let's assume
number of nickels is n
total number of coins is 21
so, number of dines will be 21-n
1 nickel =$0.05
1 dimes=$0.10
total value is 1.65
so, we can set up equation
now, we can solve for n
so, number of nickels is 9
number of dimes is 21-9=12..........Answer
(b)
we are given
value of the nickels =5n
we know that
value of dimes =2* value of nickels
so, we can plug it
value of dimes =2*5n
value of dimes =10n...............Answer
