Question

a lending library has a fixed charge of rs x for the first day and for the subsequent days it is rs y per day. a man paid rs20 for 5 days. write a linear equation for this information & draw its graph​

Answer 1

Answer:

Total charge = a

No. of days = b

Amount charged during first day = x

Amount charged during subsequent days = y

a = x + b(y-1)

the equation, a = x + b(y-1) is not a linear equation in two variables. Thus a graph can not be plotted.
