The line graph shows the sales figures for a company in the first half of a given year. Which month had the sales increased the most from the previous month? By how much did they increase?

Our months are found down here, and the amount of money is found over here. So let’s go each month and write how much was sold per month. During month number one, 10000 dollars were sold. And even though it says 10, it says that the sales are in thousands of dollars, so it’s 10000.

During month number two, 16000 dollars were created by sales. During month number three, there were 12000. Month number four had 14000. Month number five had 18000. And month number six had 4000.

So we want to know which month had the sales increased the most from the previous month. From month one to month two, it increased 6000. From month two to month three, it decreased 4000. From month three to month four, it increased 2000. From month four to month five, it increased 4000. And from month five to month six, it decreased 14000. So the biggest increase was 6000 dollars, and that was from month one to month two.

And we’re asked which month had the sales increased the most from the previous month. So we would say the second month. And the amount that it increased was 6000 dollars. So this will be our final answer.
