An attendant collected 77 coins from a parking meter. the value of the coins was $9.15, and there were six more dimes than quarters. which system models this situation? assume the coins are nickels(n), dimes (d), and quarters (q). a. {n + d + q = 77 {5n + 10d + 25q = 9.15 {d + q = 6 b. {n + d + q = 915 {5n + 10d + 25q =9.15 {d - q = 6 c. {n + d + q = 77 {0.05n + 0.10d + 0.25q = 9.15 {d - q = 6 d. {n + d + q = 915 {0.05n + 0.10d + 0.25q = 77 {d + q = 6
