The revenue, R R , she makes from selling a batch of n n ponchos is given by the function R(n)=20n R(n)=20 n , and the expenses, E E , that she incurs from producing a batch of n n ponchos is given by the function\newlineE(n)=10n E(n)=10 \cdot \sqrt{n} \text {. } \newlineLet P P be the total profit Scarlett makes from producing and selling a batch of n n ponchos.\newlineWrite a formula for P(n) P(n) in terms of R(n) R(n) and E(n) E(n) .\newlineP(n)= P(n)= \newlineWrite a formula for P(n) P(n) in terms of n n .\newlineP(n)= P(n)=\square
  1. Define Profit Function: Define the profit function in terms of revenue and expenses. Profit is calculated by subtracting expenses from revenue. Profit P=REP = R - E
  2. Write Formula for P(n): Write the formula for P(n) using the given functions for R(n) and E(n).\newlineWe are given R(n)=20nR(n) = 20n and E(n)=10nE(n) = 10\sqrt{n}.\newlineSo, P(n)=R(n)E(n)P(n) = R(n) - E(n)
  3. Substitute Expressions: Substitute the expressions for R(n)R(n) and E(n)E(n) into the profit formula.P(n)=20n10nP(n) = 20n - 10\sqrt{n}
  4. Simplify Expression: Simplify the expression for P(n)P(n) if possible.\newlineThe expression 20n10n20n - 10\sqrt{n} is already in its simplest form, so we cannot simplify it further.
