Activity: To solve problems in context [LO1.6.1]

** This is a task for your portfolio – do it without your pocket calculator! Be sure that you really understand what you have to do. Consider the assessment criteria before you start! Ask your educator for the paper that you will need:

1. Page through the local newspaper and find three advertisements that offer houses for sale. The prices should all be more than one million rand. Cut out the advertisements neatly and paste them on your sheet of paper. Calculate the combined price of the three houses.

2. Page through the newspaper again to find three examples of flats that are for sale. Also cut these out neatly and paste them on your paper. Calculate the combined price of the most expensive and the least expensive flats.

3. Now look for examples of three cars that are for sale. These must also be cut out and pasted neatly. Calculate the combined cost of the three cars.

4. Now select one house or flat and one car and calculate what you will have to pay for these items.
