The cost of producing a small transistor radio set consists of P22.00 for labor and P36.00 for materials. The fixed ch operating the plant are P100,000 per month. The variable cost is P1.50 per set. The radio set can be sold for P78.00 Determine

1. How many sets must be produced per month to break-even?

2. How many sets must be produced per month to each at least P 100,000

3. If the price drops by 10% after selling 5,000 units, how many sets must be produced per month to
