Answer:
31,500
Explanation:
Cost function, C (x) = 2 x + 4500
Revenue function, R (x) = 5 x
Profit = Total revenue - Total cost
= R(x) - C(x)
= 5 x - [2 x + 4500]
= 3 x - 4,500
If company sells 12,000 boxes, then profit will be:
= 3 x - 4,500
= 3(12,000) - 4,500
= 36,000 - 4,500
= 31,500
Therefore, 31,500 is the profit earn by the company by selling 12,000 boxes of cereal.
