Answer:

for seven days, while

Susy paid < 21 for the book she kept for five days. Find the fixed charge and the

charge for each extra day,

Answer 2

It's good to see you studing...

Let's get it solved...

Step-by-step explanation:

Let the fixed charge be Rs. x

and the extra charge be Rs. y

x+4y=27⟶(i)

x+2y=21⟶(ii)

On substracting (i) and (ii),

2y=6

y=3

putting y in (i),

x+4(3)=27

x=15

∴x=Rs.15 and y=Rs. 3

∴ Fixed charge =Rs. 15

∴ Charge for each extra day =Rs. 3 .
