Answer:
Profit = 51300 thousand dollars
Explanation:
Cost function in thousands of dollars is given by C(x) = 45 x + 8700, where x represent number of tricycles sold.
Revenue of function R(x) = 75 x
We have the expression for profit = Revenue - Cost
Number of tricycles sold = 2000
Revenue = 75 * 2000 = 150000 thousand dollars
Cost = 45 * 2000 + 8700 = 98700 thousand dollars
Profit = 150000 - 98700 = 51300 thousand dollars
