Explanation:

Given

In 1 hour:

Amy: 8 walls or 6 outlets

Bill: 5 walls or 5 outlets

Solving (a): Amy

(i) Opportunity cost of the outlets

This can be represented as:

[tex]8\ walls = 6\ outlets[/tex]

Divide both sides by 2

[tex]4\ walls= 3\ outlets[/tex]

This means that: for 3 outlets done, 4 walls are not done.

(i) Opportunity cost of the walls

This can be represented as:

[tex]6\ outlets = 8\ walls[/tex]

Divide both sides by 2

[tex]3\ outlets = 4\ walls[/tex]

This means that: for 4 walls done, 3 outlets are not done.

Solving (b): Bills

(i) Opportunity cost of the outlets

This can be represented as:

[tex]5\ walls = 5\ outlets[/tex]

Divide both sides by 5

[tex]1\ wall = 1\ outlet[/tex]

This means that: for 1 outlet done, 1 wall is not done.

(i) Opportunity cost of the walls

This can be represented as:

[tex]5\ outlets = 5\ walls[/tex]

Divide both sides by 5

[tex]1\ outlet = 1\ wall[/tex]

This means that: for 1 wall done, 1 outlet is not done.
