Okay, here are the steps I took to solve this problem:
* Kris's mother gave her $10
* She purchased 2 bags of wooden beads at $2.99 each ($5.98 total)
* She purchased 1 bag of glass beads for $3.99
* She purchased a bead storage tray for $2.49
* She purchased a pattern book for $4.00
* The total cost of the 5 items is $16.46
* Since Kris started with $10, subtracting the $16.46 in costs from the $10 leaves her with -$6.46 remaining
So the amount of money Kris has left after purchasing the 5 items is -$6.46
