Dana and Tara have decided to visit their local supermarket to prepare dinner for their friends. While there, they decided to make a table for the potatoes that cost \( \$ 3.25 \) per pound. \begin{tabular}{|c|c|} \hline Number of Pounds & Cost (\$) \\ \hline 1 & 3.25 \\ \hline 2 & 6.50 \\ \hline 3 & 9.75 \\ \hline 4 & 13.00 \\ \hline \end{tabular} What if the local store decided to charge \( \$ 0.50 \) for a potato bag? Model an equation to represent the cost per pound of potatoes and the bag of potatoes.

Consider the following reaction: 2H2S(g)+SO2(g)⇌3S(s)+2H2O(g) A reaction mixture initially containing 0.500 M H2S and 0.500 M SO2 was found to contain 1.1\times 10−3 M H2O at a certain temperature. A second reaction mixture at the same temperature initially contains [H2S]= 0.240 M and [SO2]= 0.320 M .Calculate the equilibrium concentration of H2O in the second mixture at this temperature.

Texts: A news item is spreading by word of mouth through a population of size 40,000 people. After t days, the number of people in thousands who have heard the news is given by the following equation: 40v = 0 = 1 + 50e^(-1.6t). Approximately how many thousand people have heard the news after 9 days? (Give your answer correct to at least three decimal places.) 39.998 thousand people. (b) Calculate the derivative r'(t). 3200e^(-1.6t) * f'(t) = 1 + 50e^(-1.6t)^2. (c) At what rate is the news spreading after 10 days? Give your answer correct to at least four decimal places. 0.0003 thousand people per day. (a) Compare the function f to the solutions to the different forms of the logistic growth model from this lesson. Enter the differential equation in terms of y that corresponds to this solution. dy/dt = 64y(40 - y) at t = 1600. (e) How many people have heard the news when its rate of spread is 15.96 thousand people per day? (There are two answers. Give your answers correct to the nearest whole person.) 19000 people (smaller value) and 21000 people (larger value). At what two times is the news spreading at a rate of 15.96 thousand people per day? Give your answers correct to at least three decimal places. 15.956 days (smaller value) and [larger value]. What is the fastest rate at which the news spreads? (Give your answer correct to at least three decimal places.) 2.186 thousand people per day.
