Leilani has $5.50. Her mother gives her $2.75, and her sister pays her back $1.80 that she had borrowed. Leilani goes to the store and spends $3.89. How much money does she have left?

She starts off with $5.50. Her mom gives her $2.75. ($5.50+ $2.75= $8.25 )  Her sister then pays back $1.80 which she had owed. Which is 8.25 +1.80= 10.05. She then spends $3.89. $10.05 - $3.89 = 6.16

The answer is 6.16. Lelani has $6.61 left.
