Step-by-step explanation:
We know that
A markup is the ratio of Gross Profit Margin to C<span>ost
</span>so
Markup Percentage = Gross Profit Margin/Unit Cost
Gross Profit Margin=Sales Price – Unit Cost------> $39.99-<span>$6.95----> $33.04
</span>Markup Percentage = $33.04/$6.95------> 4.7540------> 475.40%
the answer is
475.40%
