Ben buys a bicycle on lay-bye for R3 200 - NSC Mathematical Literacy - Question 1 - 2017 - Paper 1

The balance after the deposit can be calculated using:

$\text{Balance} = \text{Purchase Price} - \text{Deposit}$

Substituting the values:

$\text{Balance} = 3200 - 750 = 2450$

Thus, the remaining balance is R2450.

The total amount paid can be calculated as follows:

$\text{Total Amount Paid} = \text{Deposit} + (\text{Monthly Payment} \times \text{Number of Payments})$

Substituting the values:

$\text{Total Amount Paid} = 750 + (300 \times 5) = 750 + 1500 = 2250$

Therefore, the total amount paid after the deposit and five instalments is R2250.

The rate per kilowatt-hour (kWh) is given as 0.8865 R/Kwh. To convert this to cents, we multiply by 100:

$\text{Rate in cents} = 0.8865 \times 100 = 88.65\text{ cents}$

Thus, the rate is 88.65 cents per kWh.

To calculate the total amount charged, we compute:

$\text{Total Charged} = \text{Rate} \times \text{Quantity}$

Substituting the values:

$\text{Total Charged} = 0.8865 \times 50 = 44.325 = 44.33\text{ R (rounded)}$

Therefore, the total amount charged for the 50 Kwh of electricity is R44.33.

The abbreviation VAT stands for 'Value Added Tax'.

He works for 7 hours starting at 7:30 am. The time he goes off duty can be calculated as follows:

Starting time: 7:30 am

Duration: 7 hours

Time when he goes off duty:

7:30 am + 7 hours = 2:30 pm.

Thus, he goes off duty at 2:30 pm.

His hourly rate is R26 and he works 7 hours daily. The income for four weeks (assuming 5 working days a week) is calculated as follows:

Daily income:

$\text{Daily Income} = 26 \times 7 = R182$

Weekly income:

$\text{Weekly Income} = 182 \times 5 = R910$

Income for 4 weeks:

$\text{Income for 4 weeks} = 910 \times 4 = R3640$

Thus, his income for four weeks is R3640.

The distance between Mafikeng and Port Elizabeth is 141 km.

The two cities that are equal distance from Kimberley are East London and Polokwane.

The two cities that are furthest apart are Durban and Cape Town.

To find the total number of people surveyed, we sum the values given:

$\text{Total People} = 24 + 32 + 16 + 13 + 5 = 90$

Therefore, 90 people took part in the survey.

The number of people who saved less than 20% of their income is the sum of the first two categories:

$\text{People saving less than 20\%} = 24 + 32 = 56$

Thus, 56 people saved less than 20% of their income.

The modal range is the category with the highest frequency, which is the '10-19%' category, with 32 people.

The type of graph used to display the information is a bar graph.
