Question

In a school canteen, a cup of tea costs 60p.

Answer 1

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.

What is the cost function?

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.
