Please confirm if the expressions are fully parenthesized. As they are, 100493/40000x means (100493/40000)*x. Check by graphing on a calculator or with wxMaxima that there is a region formed by the three curves.

You have titled the post "algebra 2". Does that mean that you have done calculus, or should the solution be without calculus? We usually solve maximization problems by linear programming or calculus. However, this problem can also be solved by tabulation without using calculus...

Are you doing pre-calculus or calculus? In calculus, the maximum is obtained by setting f'(t)=derivative with respect to t = 0 and solving for t. In pre-calculus, you can transform the expression by completing the squares. Ax² + Bx + C =A(x²+ (B/A)x + C/A) =A((x + (B...

If you have done functions before calculus as most students do, you can rewrite the equation in the standard form: f(x)=a(x-h)+k where the vertex is found at (h,k) or f(x)=-(3/4)(x-2)²+3 where the vertex is found at (2,3). Confirm by Calculus: f(x)=3x-3/4x^2 f'(x)=3-(3/2)...

Yes, that's correct too. In exams and in general, if the number is a "round" number like e⊃2/2, I would give the answer as e²/2=3.6945(approx.) because the latter is an approximation. This will give the exact value as the answer.
