The tax rate as a percent, [tex]$r$[/tex], charged on an item can be determined using the formula [tex]$\frac{c}{p}-1=r$[/tex], where [tex]$c$[/tex] is the final cost of the item and [tex]$p$[/tex] is the price of the item before tax. Louise rewrites the equation to solve for the final cost of the item: [tex]$c=p(1+r)$[/tex]. What is the final cost of a [tex]$40$[/tex] item after an [tex]$8 \%$[/tex] tax is applied?

Compounds are substances made up of two or more different elements that are chemically bonded together. The smallest unit of a compound is a molecule, consisting of atoms which are in turn made up of subatomic particles: protons, neutrons, and electrons. Chemical bonds link these particles, determining the structure and properties of the compound.
