I'm trying to get how many of each model to buy so daily production is maximised.
1) F300 model cost $350,000 & S250 cost $220,000
2) At least one third purchase should be F300
3) Maintenance for F300 is $12,000 & S250 is $7,500. Total maintenance budget is 120,000
4) F300 will produce 125 units & S250 will produce 81 units

Thanks.
 
d9 is total cost i.e. 1,010,000
e9 is total maintenance i.e. 34,500

D9:F9 (total cost, total maintenance, total unit output)
