I don't understand what this question

Just desserts buys cheesecakes from general bakeries at $33.60 per cheesecake. It then cuts each cheesecake into 16 slices and sells them to customers at$6.50 per slice. Calculate the rate of markup on cost and the rate of markup on selling price.

I run into trouble when i try to calculate the markup on cost because the formula is MarkUP = Selling price - Cost

Sorry, I don't understand your difficulty . . .

Just Desserts buys cheesecakes from general bakeries at $33.60 per cheesecake. It then cuts each cheesecake into 16 slices and sells them to customers at$6.50 per slice.
Calculate the rate of markup on cost and the rate of markup on selling price.

The cost is: .$\displaystyle \frac{\$33.60}{16} \:=\:\$2.10$ per slice.

Each slice is sold for $6.50. The markup is: .$\displaystyle M \:=\:\$6.50 - 2.10 \:=\:\$4.40$per slice. Rate of markup on cost: .$\displaystyle M_c \:=\:\frac{4.40}{2.10} \:=\:2.095238095 \;\approx\;209.5\%$Rate of markup on SP: .$\displaystyle M_s \;=\;\frac{4.40}{6.50} \;=\;0.676923077 \;\approx\;67.7\%\$
