Find the markup and the selling price of the following item. Round answers to the nearest cent. A chemistry set costing $27.50,
postnew [5]

Let x be marked up price. We have been given that a chemistry set costing $27.50, marked up 32% on cost.

x=27.50\times\frac{32}{100}

x=27.50\times.32

x=8.8

Therefore, mark up price is $8.80.  

Since we know that selling price of any item equals the sum of cost and mark-up price of the item.

Let us find selling price of our chemistry set.  

\text{Selling price of chemistry set}=27.50+8.8

\text{Selling price of chemistry set}=36.30      

Therefore, the selling price of the chemistry set is $ 36.30.
