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 $19,000 was incurred. The profit associated with each unit sold was $280. 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) = 
x + 19,000
B. t(x) = 280x + 19,000
C. t(x) = 280x - 19,000
D. t(x) = 19,000x - 280
