Question 822750

Hi,
The sales tax {{{highlight_green(x)}}} on a $300 purchase is $16.50. 
{{{x*300 = 16.50}}},  x  = {{{100(16.50/300) }}}
 = 5.5% sales tax
What would be the total cost of a purchase that is marked at $450?
 {{{.055*450 }}} = $24.75
total cost of a purchase: $450 + $24.75 = $474.75
