Question 1059501
A jar contains only​ pennies, nickels,​ dimes, and quarters. There are 1616 ​pennies, 2121 ​dimes, and 1818 quarters. The rest of the coins are nickels.
---------------------------------------------
 There are 7777 coins in all. How many of the coins are not​ nickels? If n represents the number of nickels in the​ jar, what equation could you use to find​ n? 
--------------------------
# of nickels = n =  7777-(1616+2121+1818) = 2222
