Profit Planning with Taxes Carron Net Company manufactures sports nets for virtually every outdoor sport. Assume Carron sells nets for $50, on average, per unit. Last year, the company manufactured and sold 28,500 nets to obtain an after-tax profit of $261,250. Variable and fixed costs follow. Variable Costs per UnitFixed Costs per YearManufacturing$20Manufacturing$220,638Selling and administrative4Selling and administrative193,800Total$24Total$414,438 Required a. Determine the tax rate the company paid last year. Note: Round your answer to the nearest whole percentage. Answer 1 % b.What unit sales volume is required to provide an after-tax profit of $380,000?

Problem 1: A. Consider a second-order system with the transfer function $$G(s) = \frac{\alpha}{s^2 + \beta s + \alpha}$$ where $\alpha$ and $\beta$ are positive numbers. State if the settling time $T_s$ and peak time $T_p$ of the step response increase, decrease, or remain the same under the following two situations, and fill the following table. No explanation is needed. $\alpha$ remains constant while $\beta$ decreases $\beta$ remains constant while $\alpha$ increases $T_s$ $T_p$ (Note: $T_p = \frac{\pi}{\omega_n \sqrt{1 - \zeta^2}}$ and $T_s = \frac{4}{\zeta \omega_n}$. Here, $\omega_n$ and $\zeta$ are the natural frequency and damping ratio, respectively.) Figure 1 B. Consider three second order systems, whose poles are shown in Figure 2 as blue, red, and green, respectively. Compared to System 1, just mention if the % overshoot of Sys- tem 2 and System 3, increase, decrease or remain the same. No explanation is needed. (Note that $\%OS = e^{\frac{-\pi \zeta}{\sqrt{1 - \zeta^2}}} \times 100$.) Figure 2 For reference, System 1 Poles are also shown in (b) and (c) in gray.
