Solution
Before adding tax, the combined cost of the three items is . The 5% tax on $15.00=$0.75, and so the total cost of the three items, after tax is added, is
$15.00+$0.75=$15.75. Note that we could have calculated the 5% tax on each individual item, however doing so is less efficient than calculating tax on the
15.00
total.
