Kyle has a total of 16 coins in his pocket. All the coins are nickels or quarters, and they have a total value of $2.20. How many nickels does Kyle have?

n = nickels                               value = 5n

q = quarters = 16-n                  value = 25 (16-n)           summed = 220

 

5n       +    25(16-n)          = 220             solve for n = the number of nickels
