1. A manufacturer knows that 8% of the articles he makes are faulty. a) Calculate the number of articles he must make in order to supply 690 perfect articles

He sells the 690 articles at P1.95 each in order to make a profit of 45% of his expected manufacturing costs.

b) Calculate his expected manufacturing costs

c) If the actual manufacturing cost was P78 more than he expected, calculate the actual profit he makes and express this as a percentage​

Me find the measure to side a and the process to solve the problem you appreciate it : )
