Mb, I asked the wrong question the first time, this is the real one
Daniel has 23 coins in nickels and dimes in his pocket, for a total of $2.20. How many of each coin does he have?
0.05n + [?]d = 2.20; n + d = [?]
0.05n + [0.10]d = 2.20; n + d = 23
Use elimination to solve the following equation:
0.05n + [0.10]d = 2.20
n + d = 23
