Ques 2.1.5

Solution

From Queenstown to Bloemfontein return trip

RT = R410 ? 2

= R820 CA

Total travelling cost

= 12 ? R820 M

= R9 840 CA

OR Number of trips = 2 ? 12 M

= 24 CA Total travelling cost = 24 ? R410 RT

= R9 840 CA

OR

One way cost for a year RT

= R410 ? 12 M

= R4 920

Total traveling cost = R4 920 ? 2 M

= R9 840 CA OR

RT M Traveling cost = R410 ? 2 ? 12 M

=R9 840 CA

Explanation 1RT correct fare
