Mrs. Scanlon has raised $31,012 for her daughter's dance competition. Her solo dance will cost $18,302, her duet will cost $7,294 and her two group dances will each cost $1,202. 

Part 1: Round to estimate if Mrs. Scanlon will have enough money to cover the cost of her daughter's dance competition.

Part 2: Solve to find the exact amount that Mrs. Scanlon will need to pay for the dance competition.

Part 3: Solve to find how much money Mrs. Scanlon will have left over after she pays for the dance competition. 

Part 1: *answers may vary based on rounding*

$18,000 + $7,000 + $1,000 + $1,000 = $27,000

Part 2:

$18,302 + $7,294 = $25,596

$1,202 + $1,202 = $2,404

$25,596 + $2,404 = $28,000

Part 3: 

$31,012 - $28,000 = $3,012
