1. The problem statement, all variables and given/known data Aggregate # of nickels and dimes = 20 coins. If the ratio between nickels and dimes is 2:3, what is cent value of 20-coin set? 2. Relevant equations 2x = 3y 3. The attempt at a solution 20 = nickels(x)+dimes(y); ratio = 2x:3y; 2x = 3y; y = 2x/3 20 = x + 2x/3; x = 12 nickels; 6 dimes? ...confused from there.
