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

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

Hence, the manager sold the book shelf at $235.2
-2(x-6)+7=35
-2x+6+7=35 (Distributive property)
-2x+13=35 (Simplify, combine like terms)
-2x+13-13=35-13
-2x=22
-2x/-2=22/-2
X=-11
Cost/(number of cassettes) = $14.50/2 = x/15
Multiply by 15 to solve
15*($14.50/2) = x = $108.75
15 cassettes will cost $108.75.
