Worked Solution & Example Answer:The graphs below show the water tariffs for Cape Town and Johannesburg - NSC Mathematical Literacy - Question 1 - 2018 - Paper 1

State the type of graph used to represent this data.

Arrange Cape Town's percentage increase in descending order.

Identify the step that indicates the largest increase (in rand) in Cape Town's water tariff from 2016/17 to 2017/18.

Determine in which ONE of the two cities water is more expensive.

Calculate the cost of 3.5 kL of water in Johannesburg during 2017/18.

Is the data given categorically or numerically?
