A lending library has a fixed charge for the first three days and an additional charge for each day thereafter. Saritha paid ₹27 for a book kept 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:

See the attachment.

Hope u understand

In the given question, 5₹ is the fixed charge and 3₹ is the charge for each extra day.

A fixed charge is a fee or cost that remains constant and does not vary with changes in usage or consumption.

Let the fixed charge for the first three days be x and the charge for each extra day be y.

From the given information, we can set up two equations:

For Saritha: [tex]\rm 3x + 4y = 27 -----(equation 1)[/tex]  

For Susy: [tex]\rm 3x + 2y = 21 -----(equation 2)[/tex]

We can solve for x and y by using elimination or substitution:

Using elimination, we can multiply the second equation by 2 and subtract it from the first equation:

[tex]\rm 3x + 4y = 27[/tex]

[tex]\rm - (6x + 4y = 42)[/tex]

Solving above equations, we get:

[tex]\rm -3x = -15[/tex]

[tex]\rm x = 5[/tex]

Substituting x = 5 into one of the equations, we can solve for y:

[tex]\rm 3(5) + 4y = 27[/tex]

[tex]\rm 15 + 4y = 27[/tex]

[tex]\rm 4y = 12[/tex]

[tex]\rm y = 3[/tex]

Therefore, the fixed charge is ₹5 and the charge for each extra day is ₹3.

When Linnaeus began classifying organisms in the 1700s, he categorized them as plant, animal, or mineral. These kingdoms were later revised to exclude minerals and expanded to include animals, plants, fungi, protists, and bacteria. Which of the following best explains a reason for this change? (2 points)

Group of answer choices

As new organisms were discovered, new kingdoms were created to sort them based on ability to interbreed.

It was discovered that the organisms in each of the five kingdoms have a different method of obtaining nutrients and are therefore fundamentally different.

Technological advances led to the discovery of single-celled organisms and increased our understanding of relationships between organisms.

Genetic research led to the discovery that each of these five kingdoms has a unique evolutionary ancestor.
