If labor (x) costs $249 per unit, materials (y) cost $162 per unit, and capital (z) costs $ 7

If labor (x) costs $249 per unit, materials (y) cost $162 per unit, and capital (z) costs $ 77 per unit, write a function for total cost.

Total Cost = Labor Total Cost + Materials Total Cost + Capital Total Cost
Total Cost = 249x + 162y + 77z
