Question

A pen costs twice as much as a book while a set costs shs.2,000 more than a book. If the three items cost shs.11,000, What is the cost of each item

Answer 1

Step-by-step explanation:

let the price of pen be rs 2y

let the price of book be rs y

let the price of a set of pen be rs 2000+y

Therefore

2y+y+2000+y= 11000

4y = 9000

y= 2250

Therefore,

price of pen = 4500

price of set of pen = 4250

price of book = 2250
