T-Shirt Profit The latest demand equation for your Yoda vs. Allen T-shirts is given by $q = -60x + 900$ where $q$ is the number of shirts you can sell in one week if you charge $x per shirt. The Student Council charges you $200 per week for use of their facilities, and the T-shirts cost you $7 each. Find the weekly cost as a function of the unit price $x$. C(x) = Hence, find the weekly profit as a function of $x$. P(x) = Determine the unit price (in dollars per T-shirt) you should charge to obtain the largest possible weekly profit. $x = $ per T-shirt What is the largest possible weekly profit (in dollars)? $

5.The rubber tube of a bicycle tyre is inflated to an absolute pressure P?. Considering that the loss of pressure with time is due to the diffusion of N? and O? through the rubber tube, show that the time it takes for the pressure to reduce to P? is given by the following equation, assuming that the diffusion follows Fick's law with a linear profile through the tube wall and an effective diffusion coefficient D<sub>AB</sub>. The surface area, volume and rubber wall thickness of the tube are S m², V m³, and w m, respectively. The atmospheric pressure outside the tube is P<sub>o</sub>. t = \frac{wV}{SD_{AB}} \ln{\frac{P_1 - P_o}{P_2 - P_o}} 6. Use the equation of Question 5 to calculate the diffusion coefficient of the rubber tube if the pressure in the tube is reduced from 3 bar to 2 bar in six months time, taking the atmospheric pressure as 1 bar. The diameter of the cross-sctional area of the tube is 50 mm, and if the tube is cut, the length of the tube, approximating it to a cylinder, is 1.8 m. The tube thickness is 1 mm.
