a pencil, pad of paper, and erase cost P42. the paper costs P5 more than the erase, while the pencil cost P2 more than the paper. find the cost of each item

Sagot :

Okay so here how i solve it 
all 3 of them make a cost of P42
So in order to solve it divide 42 by 3 
42/3 = 14
Pencil = 14
Paper = 14
Eraser = 14
The paper cost "P5" more than the eraser
All you need to do is add 5 on the paper and minus 5 on the eraser.
Paper =19
Eraser = 9
Pencil = 14
Then the pencil costs "P2" more than the paper
Add 2 pesos on the pencil
Pencil= 16
then minus 2 on the paper 
Paper =17
So that makes them 
Pencil = 16
Paper=17
Eraser =9 
________
total : P42.00
So that makes the answer 
the answer is => Pencil = P16
                                Paper=P17
                             Eraser = P9
