7. Exercise problems VII

Form the pair of linear equations for the following problem and find their solution by substitution method.

 

The taxi charges in a city consist of a fixed charge together with the charge for the distance covered. For a distance of \(10km\), the charge paid is \(Rs.105\) and for a journey of \(15 km\), the charge paid is \(Rs.155\). What are the fixed charges and the charge per \(km\)? How much does a person have to pay for travelling a distance of \(25 km\).

 

Fixed charge \(=Rs.\)

 

Charge per \(km=Rs.\)

 

Total cost for travelling \(=Rs.\)
