Explanation: Value of 1 nickel coin is $5$cents Value of 1 quarter coin is $25$cents Value of $1 is $100$ cents
Value of $3.45 is $345$cents Let the number of nikels be $n$and the number of quarters be $q$So $n + q = 25$(1) $5 n + 25 q = 345$(2) multiplying eqn. (1) by 5 and then subtracting from eqn.(2) we get $5 n + 25 q = 345$(2) $5 n + 5 q = 125$(1) 20q =220 or q=11 ; n= 25-11=14 $11$quarter coins and $14\$ nickel coins were in the bag.[Ans]
