The manager at Gabriela's Furniture Store is trying to figure out how much to charge for a book shelf that just arrived. The boo
Burka [1]

Answer: The manager sold the book shelf at $235.2

Step-by-step explanation:

Since we have given that

Wholesale price of the book shelf = $147.00

But Gabriela's Furniture Store marks up all furniture by 60%.

So, Mark up value is given by

\frac{60}{100}\times 147\\\\=\frac{8820}{100}\\\\=\$88.2

So, the new price that the manager sold the book shelf is given by

147+88.2\\\\=\$235.2

Hence, the manager sold the book shelf at $235.2
