4 dollars or 13 dollars
Step-by-step explanation:
Revenue is the income or increase in net assets that a commercial organization have as a result of offering services.
Revenue is the product of selling price per goods and the number of goods sold. That is:
Revenue = selling price per goods * number of goods sold
Given the revenue function:
R=-n² +17n +200; where n is the increase in the original price of T-shirt.
Since the council wants to make a revenue of $250, hence:
-n² +17n +200 = 250
-n² + 17n - 50 = 0
Solving using a calculator gives:
n = $4 or $13 (to the nearest whole number)
