A pizza manufacturer purchases cheese, pepperoni, and tomato paste. The prices of these ingredients in 1997, 1999,
and 2001 were:
Ingredient 1997 1999 2001
Cheese (per kg) £1.75 £2.65 £3.10
Pepperoni (per kg) £2.25 £2.87 £3.55
Tomato paste (per litre) £0.60 £1.10 £1.35
(a) Calculate a simple aggregate price index for the prices
in 1999 and 2001 using 1997 as the base period.
(b) What additional information would you need in order
to calculate a weighted aggregate price index to
measure these price changes?

b. x- 48 =120

step-by-step explanation:

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.

the answer is (-8,-5)

step-by-step explanation:

the endpoint to midpoint is half the length. the length is (-2,-1) so when you are at the midpoint just add it to it to find your answer -6+(-2)= -8 and -4+(-1)=-5 so (-8,-5)
