A car repair work shop uses large numbers of filters, costing 300naira each, and plug, costing 400naira each. The work shop owner allows 30,000naira for these parts and needs at least twice as many filters as plugs. There must also be at least 50 filters and 20 plugs.
What is the largest number of parts that can be brought, and in what way?
If it is decided to buy as many plugs as conditions allow, how many of each part can be brought?
