Answer provided by our tutors
1 nickle = 5 cents
1 dime = 10 cents
let
n = the number of nickels, n>0, n is integer
d = the number of dimes, d>0, d is integer
a jar containing only Nickels and dimes contains a total of 50 coins:
n + d = 50
the value of all the coins in the jar is $3.25 = 325 cents:
5n + 10d = 325
by solving the system of equations:
n + d = 50
5n + 10d = 325
we find:
n = 35 nickles
d = 15 dimes
