Answer:
$27.54
Step-by-step explanation:
The straightforward way to do this is to compute the tax and total on each amount, then add those together. There is an easier way.
($12.50 + 0.08·12.50) + ($13.00 + 0.08·13.00) = $12.50·1.08 +13.00·1.08
= 1.08($12.50 +13.00)
= 1.08·$25.50
= $27.54
Together, Ron and Harry paid a total of $27.54.
