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.

Y=1/2 x +4
Slope = x coefficient = rise/run = 2/4=1/2
Y intercept= constant = 4
Answer:
250.9
Step-by-step explanation:
1) Add all the numbers = 2007
2) Divide by the number of integers present = 2007/8
3) Round to the nearest tenth = 2007/8 = 250.875 = 250.9
