Question

Sugar costs 80p for ev kilograms. 2 Copy the axes below g a table of values, plot ir axes to show the relat ween the mass of sugar cost. Cost (p) 600- 500- 400- 300- 200- 100+ 0 3 4 5 Mass (kg) 8 9​

Answer 1

The graph of the relationship y = 40x is added as an attachment

The table of values is

x y = 40x y

1 40 * 1 40

2 40 * 2 80

3 40 * 3 120

4 40 * 4 160

Showing the relation between the mass of sugar and its cost

From the question, we have the following parameters that can be used in our computation:

Sugar costs 80p for every 2 kilograms.

Let y = Cost of sugar and x = the weight

So, we have

y : x = 80 : 2

This gives

y/x = 80/2

y/x = 40

Rewrite as

y = 40x

Using a table of values, we have

x y = 40x y

1 40 * 1 40

2 40 * 2 80

3 40 * 3 120

4 40 * 4 160
