Given -

s(d) = d³ + 9

To Find -

What is the maximum number of sales per day on the interval 0 < d ≤ 3 =?

Step-by-Step Explanation -

We are given that the function s(d) = d³ + 9

Lies between 0 < d ≤ 3.

So, the maximum number of sales per day is at d = 3

Putting d = 3 in s(d) = d³ + 9

s(d) = (3)³ + 9

s(d) = 27 + 9

s(d) = 36

Final Answer -

The maximum number of sales per day = 36
