5) It is known that there is a linear relationship between
the cost of a taxi, C, in dollars and the distance travelled, d, in kilometres. This relationship can be represented by a straight line equation. When I travel 15km the taxi costs
me $32. 20 and when I travel 20km with the same company, the taxi costs
me $41. 70.
Develop algebraically, the linear equation, C = 1. 9 d + 3. 7, which
shows the relationship between the cost of the taxi, C, in terms of the
distance travelled, d
