The expression for the cost function is cost=60y.
We have given that,
a cup of tea costs 60p.
We have to determine the cost function.
<h3>What is the cost function?</h3>
In mathematical optimization and decision theory, a loss function or cost function is a function that maps an event or values of one or more variables onto a real number intuitively representing some cost associated with the event. An optimization problem seeks to minimize a loss function.
Cost=no of cups(price for one cup)
cost=60y
Therefore the expression for the cost function is cost=60y.

Answer: C.) Nitrogen-fixing bacteria in the soil
Step-by-step explanation: "Nitrogen-fixing bacteria in the soil and within the root nodules of some plants convert nitrogen gas in the atmosphere to ammonia. Nitrifying bacteria convert ammonia to nitrites or nitrates. Ammonia, nitrites, and nitrates are all fixed nitrogen and can be absorbed by plants."-https://www.Khanacademy.org/
