Answer 1

Hint: As we know that the above given question is a word problem. A problem is a mathematical question written as one sentence or more describing a real life scenario where that problem needs to be solved by the way of mathematical calculation. We can solve the given problem by applying the method of mathematical numbers and then solve them.

Complete step by step answer:
We need to first understand the requirement of the question i.e. which week has the sale greater and by how much compared to the other.We have been given that the value of the book sold in the first week is $285121$. And the value of the book sold in the second week is $400768$.

So we can find the total number of books sold in the first and second week $ = 285121 + 400768 = 685889$.
Therefore the total sale of two weeks is $685889$.
Now we can see that the sale in the second week is higher from the first as $400768$ is greater than $285121$.
So the increase in sales in the second is $400768 - 285121 = 115647$.

Hence the total value for the sales in two weeks is $685889$ and the sale in the second week is more than the sale in the first week by $115647$.

Note: We should always be careful what the question is asking i.e. sale for the both weeks together and in which week the sale is greater. Based on the requirement and by observing all the necessary information that is already available in the question we gather the information and then create an equation or by unitary method whichever is applicable, then we solve the problem and then verify the answer by putting the value in the problem and see whether we get the same answer or not.
