Best ResponseYou've already chosen the best response.0Value of all the nickels in bank=(Value of 1 nickel) * n =($0.05)*n Value of all the dimes in bank=(Value of 1 dime) * d =($0.10)*d The value of all the coins=($0.05)*n + ($0.10)*d which is equal to $2.45

Best ResponseYou've already chosen the best response.0So, the second equation ($0.05)*n + ($0.10)*d=$2.45 .................eqn(2)

Best ResponseYou've already chosen the best response.0Let the no. of nickels be x. Let the no. of dimes be y. four more nickels than dimes mean no of dimes(y)+4=no of nickels(x) Cn u just tel me the value of 1 nickel and dime?
