Hayley saved $124 to spend on her vacation the first day she spent 3/8 of her savings the second day she spent 2/5 of what remained how much money in dollars did she have at the beginning of day 3

$46.50

Step-by-step explanation:

Now to do this, you need to first determine how much she spent on the first day.

She had a total of $124 and she spent 3/8 of it. This means that there are only 5/8 of it left. What is 5/8 of $124? We do that by multiplying it by the fraction.

After the first day, she has $77.50 left. On the second day, she spent 2/5 of what she had left. So that means she would have only 3/5 of what she had left.

So she will have only $46.50 left at the beginning of the third day.

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:

9² + 15² = 306.   this is not equal to the square of the longest side ( that square being 395.   answer c is correct.
