Concept/skill: 
Use ratio and rate reasoning to solve real-world and mathematical problems, e.g., by reasoning about tables of equivalent ratios, tape diagrams, double number line diagrams, or equations.

Problem/activity:
You’re mixing ingredients for cookies. The recipe says to combine 6 tablespoons, or ¾ stick, of butter with 1 cup of sugar. You accidentally mix in a whole stick of butter (8 tablespoons) with the cup of sugar. How can you fix this?


Answer: 
Yes. This problem solves a real-world problem involving mixing ingredients for cookies. A student doing this problem would need to reason about equivalent ratios of butter amounts to sugar amounts.

Now, assess whether the following problem or activity is 'aligned' with the given Common Core standard in Mathematics.

standard_description: For exponential models, express as a logarithm the solution to ab^(ct) = d where a, c, and d are numbers and the base b is 2, 10, or e; evaluate the logarithm using technology.
problem_activity: Task
A cup of hot coffee will, over time, cool down to room temperature.  The
principle of physics governing the process is Newton's Law of Cooling.
Experiments with a covered cup of coffee show that the temperature (in
degrees Fahrenheit) of the coffee can be modelled by the following
equation
$$
f(t) =  110e^{-0.08t}+75.
$$
Here the time $t$ is measured in minutes after the coffee was poured into
the cup.
Explain, using the structure of the expression $110e^{-0.08t} + 75$,
why the coffee temperature decreases as time elapses.
What is the temperature of the coffee at the beginning of the experiment?
After how many minutes is the coffee $140$ degrees?
After how many minutes is the coffee $100$ degrees?
