Answer 1

Answer:

I think answer is x+4y=27

Step-by-step explanation:

fixed charge for 3 days = x

then after,

additional charge for each day = y

Aarushi paid ₹27 for 7 days . so equation is

x + 4y = 27

Answer 2

Answer:

Given :-

A lending library has a fixed charge for the first three days and an additional charge for each day thereafter.

Saritha paid Rs 27 for a book kept for seven days, while Susy paid Rs 21 for the book she kept for five days.

Solution :-

Let the fixed charge for first three days and each day charge thereafter be Rs x and Rs y respectively.

According to the question,

⇒ x + 4y = 27 ... (i)

⇒ x + 2y = 21 ... (ii)

Subtracting equation (ii) from equation (i), we get

⇒ 2y = 6

⇒ y = 3 ... (iii)

Putting in equation (i), we get

⇒ x + 12 =27

⇒ x = 15

Fixed charge = Rs 15

Charge per day = Rs 3.

Hence, The Fixed charge is Rs 15 and Charge per day is Rs 3.
