Cost Price = $75.
Marked up by 20%.
Selling Price = (100% + 20% ) of Cost Price.
= 120% of 75
= 1.2 * 75
= 90
Selling price = $90
Well, "of" means multiply so, you would divide 1 by 10 to get .1 then multiply that by 3 and get .03

Step-by-step explanation:
Any thing to the power 0 will always be 1
x⁰=1
(3^-1=1/3)
(4^-1=1/4)
(5^-1=1/5)
1/3+1/4+1/5=47/60
(47/60)^0=1 (as any thing to the power 0 will always be 1 )
Hope this helps you.
