Wendy has $60. She wants to buy a book that costs $26.50 and a bag that costs $19.50.
The sales tax is 13%. Does Wendy have enough money to buy both the book and the
bag? If so, how much money does she have left? If not, how much more money does
she need?
The total cost of the book and the bag is $26.50 + $19.50 = $<<26.50+19.50=46>>46.
The sales tax on the total cost is $46 x 0.13 = $<<46*0.13=5.98>>5.98.
Therefore, Wendy needs $46 + $5.98 = $<<46+5.98=51.98>>51.98 to buy both the book and the bag.
Since Wendy only has $60, she has $60 - $51.98 = $<<60-51.98=8.02>>8.02 left after buying the book and the bag. Answer: \boxed{8.02}.
