The maximum possible monthly profit of the shop is about $___
The interval over which the shop makes a profit is (___ , ___)
The maximum profit is earned when $___ is spent on advertising.

Answer 1

Answer:

The maximum possible monthly profit of the shop is about $ 4,500 .

The interval over which the shop makes a profit is (0 , 1,000 ).

The maximum profit is earned when $ 300  is spent on advertising.

Step-by-step explanation:

Answer 2

The maximum profit is the highest point on the curve at (3, 45), and since the y-value is the profit in hundreds of dollars, the maximum profit is $4500.
The shop is making a profit as long as the curve is above the x-axis, so this is over the given interval (0, 10).
The maximum profit is earned at x = 3, and the x-value is the money spent on advertising in hundreds of dollars, so this means that $300 was spent of advertising.
