Question

The total price of a cupboard,a chair and a table is $1500.The price of the cupboard is twice the price of the table.The chair is $80 cheaper than the table.Find the price of each item.

Answer 1

Let x = the price of the table

Let 2x = the price of the cupboard

Let x - 80 = the price of the chair

x + 2x + x - 80 = 1500

4x = 1580

x = $395

2x = $790

x - 80 = $315
