Question

How do you solve this question:

The cost of 3 markers and 2 pencils is $1.80. The cost of 4 markers and 6 pencils is $2.90. What is the cost of each item?

Answer 1

If you put the cost of a marker as x, and the cost of a pencil is y, then
3x+2y=?
and if you do the same for the second part of the question, you will end up with two equations with two unknowns from which you should be able to solve for x and y.

Answer 2

let the cost of a marker be x
let the cost of a pencil by y

3x + 2y = 180
4x + 6y = 290

I would triple the first equation
9x + 6y = 540
then subtract the second from that to get
5x = 250
x=50

take it from there
