Question

Tami bought a jacket that normally costs $84 at 15% markdown. She then paid 7% sales tax.

Answer 1

15%=.15
84 x .15=$12.60 discount
subtract from $84
84-12.60= $71.40
multiply by .07 sales tax
71.40 x .07= 4.998  rounded off to $5.00
total cost  $71.40 + $5.00=
$76.40 is what Tami paid for the coat

hope this helps
