One bottle of sunscreen costs $4.50.

Explanation:

Let's use b to represent the bottles of sunscreen and h for the hat.

The information in the problem yields this equation:

#1.06(2b+h)=16.43#

The tricky part is understanding the 1.06 coefficient. If there is a 6% sales tax on top of the total price, that is the same as multiplying the price by 1.06 (itself plus 6% more).

Now we can divide both sides by 1.06 to get a simpler equation:

#2b+h=15.50#

Last, we plug in the hat's price and solve for b:

#2b+6.50=15.50#
#2b=9.00#
#b=4.50#
