Question

# Need help with these math problems please. I have a test tomorrow and need someone to break these down like for a

5th grader.

- The weekly marginal profit for an output of x units is given approximately by P' (x) = 150 - x/10 0 ≤ x ≤ 40

What is the total change in profit for a change in production from 10 units per week to 40 units? Set up a definite integral and evaluate it.

2.If the marginal profit for producing x units per day is given by

P' (x) = 100- 0.02x P(0)=0

where P (x) is the profit in dollars, find the profit function P and the profit on 10 units of production per day.
