Answer:
Before taxes = $450
After taxes = $477
Explanation:
To find the purchase price, we need to find the amount equivalent to 100%.
So, if 6% is equivalent to $27, 100% is equivalent to:
[tex]100\text{ \% }\times\frac{\text{ \$27}}{6\text{ \%}}=\text{ \$450}[/tex]Therefore, the purchase price of the bike before taxes is $450 and the purchase price of the bike after taxes is $450 + $27 = $477
