A workshop sells a table ($x$) for ₹900 that costs ₹600 to make, and a chair ($y$) for ₹300 that costs ₹200 to make. Which objective maximises its profit?

Explanation

1. 01

   Write each resource as (amount used per unit) × (number of units), added over the products.

2. 02

   'At most' or 'available' gives ≤, 'at least' or 'must give' gives ≥; a profit is maximised and a cost minimised.
