Bob's auto production company has two cars (XER and YAN) it prepares to produce. Every XER needs 300 hours to manufacture all parts and 200 hours for finishing. Every YAN needs 100 hours to produce all parts but 300 hours to finish. Bob can spare at most 3000 hours for completing and 1500 hours for manufacturing parts. Due to amount of materials, number of XER's made should be at least 3 less than 75% of YAN's made. If every XER sells for $95,000 and YAN sells for $35,000 and Bob wishes to make atleast 2 YAN's, determine number of each which will maximize the profit.
