Molly has $5.65 in coins. Let the number of dimes be d, nickels be n, and quarters be q. The relationships given are n = d + 4 and q = d - 7. Each nickel is worth $0.05, each dime is worth $0.10, and each quarter is worth $0.25. The total value equation is 0.05n + 0.10d + 0.25q = 5.65. Substituting the relationships into the total value equation and solving gives us d = 18, n = 22, and q = 11. Therefore, Molly has 11 quarters.
