Answer:
6251 tapes
Step-by-step explanation:
Given: fixed cost is $10,000.
Variable cost is $0.40 to produce each tape.
Selling price is $2 per tape.
Lets assume number of tapes to be produced and sold be "x"
We know, Total cost=

∴ Total cost=

Total cost=

As given, selling price is $2 per tape.
∴ For attaining break even point, Tota cost = Selling price.

Solving the equation to find the value of x
⇒

Subtracting both side by 0.4x
⇒

Dividing both side by 1.60
⇒

∴ x= 6250
Hence, number of tapes must be sold and purchased is 6250 to attain break even in the business, however selling one more tapes will get profit is 6251.
