Answer 1

Barney spent $70 on 3 shirts and 2 pants and Robin bought 1 shirt and 4 pairs of pants for $90.

Let "x" represent the price of one shirt and "y" represent the cost of one pant.

The total cost of Barneys purchase can be represented as:

`3x+2y=70`

And the total cost of Robins purchase can be represented as

`x+4y=90`
