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​

mr. flanders’ class sold 47 doughnuts and   mr. rodriquez’s class sold 38 cartons of milk

step-by-step explanation:

let x be the number of doughnuts sold by mr. flanders’ class and y be the number of cartons sold by mr. rodriquez’s class.

1. together, the classes sold 85 items, then

x+y=85.

2. both classes earn earned $104.49 for their school. if doughnuts were sold for $1.35 each, then x doughnuts costed $1.35x. if cartons of milk were sold for $1.08 each, then y cartons costed $1.08y. hence,

1.35x+1.08y=104.49.

3. solve the system of two equations:

22 dimes and 9 nickels
