Answer: Giselle has spent more than 1/2 of her parking money.
Explanation:
She has $40 dollars and parking lot cost $2.50 and she pays $2.50 for 9 days.
you need to multiply 2.50 * 9 and equals 22.5
now you need to subtract $40 - $22.5 and equals $17.5
now we need to know what is 1/2 of 40 and is 20 since $17.5 is less than $20 Giselle has spent more than 1/2 of her parking money.
