ANSWERS: Mixed Doubles 4

It's been almost two weeks since I've posted my fourth "Mixed Doubles" puzzle, so that means it's time for me to list the people who have solved it since then:

• Grant Fikes ****
• Eric Maddy ****
• Lynn Sweeney ***
• Sam Levitin ****
• Mom ****
• Debbie Benford ****

Now just head below the break for the answers!

And here are all the correct number combinations:

ACROSS: 1/17, 2/9, 3/10, 4/12, 5/21, 6/15, 8/19, 9/2, 10/3, 11/18, 12/4, 13/20, 14/16, 15/6, 16/14, 17/1, 18/11, 19/8, 20/13, 21/5

DOWN: 1/11, 2/20, 3/5, 4/13, 5/3, 6/18, 7/8, 8/7, 9/21, 11/1, 12/16, 13/4, 14/17, 15/19, 16/12, 17/14, 18/6, 19/15, 20/2, 21/9

The two leftover clues are 7-Across and 10-Down, and the answer to those clues (which you can get by scrambling the letters in the pink squares) is FIRECRACKER: this puzzle's FINAL ANSWER!
