n represents the number of nickels
422 - n represents the number of dimes
0.05n + 0.10(422 - n) = 36.95
Can you solve for n and answer?

Are dimes and nickels the only coins he has? If he has others, I'm not sure there is a solution. Keep in mind that you have to have the same number of equations as you have unknowns10/29/19
