Answer appropriately.A microcomputer company analyzed its sales and profits and discovered a linear relationship between how many units were sold each week and the profits for that week. No matter how many microcomputers were sold, a fixed expense of $18,000 was incurred. The profit associated with each unit sold was $220. The total profit was the per-machine profits less the fixed expense. Express the weekly total profit as a function t(x) where x is the number of units sold each week.
A. t(x) = 220x - 18,000
B. t(x) = 18,000x - 220
C. t(x) = 220x + 18,000
D. t(x) = 
x + 18,000
