We know that
• The large dog cage costs $98.50.
,• The wholesale costs $63.55.
The markup is the difference between the wholesale and the retailer price, that is, it represents the earnings. Let's subtract.
[tex]98.50-63.55=34.95[/tex]Then, we divide to find the percentage.
[tex]\frac{34.95}{63.55}\approx0.55[/tex]We multiply by 100 to express the number in percentage.
[tex]0.55\cdot100=55[/tex]
