The table lists how poverty level income cutoffs(in dollars) for a family of four have changed over time. Use the midpoint formula to approximate the poverty level cutoff in 1987 to the nearest dollar. the poverty level cutoff in 1987 was _____ dollars. ( round to the nearest dollar as needed. year income (in dollars) 1970 3073 1980 8558 1990 13807 2000 17864 2004 19196

Well, let's add some humor to this math problem, shall we?

Hmm, calculating poverty levels... sounds like the income version of limbo. How low can you go?

Now, let's use the midpoint formula, which is basically the arithmetic equivalent of finding the "middle child" in a family of numbers. The formula goes like this: (Income in Year A + Income in Year B) / 2.

So, let's calculate the approximation for 1987. Drumroll, please!

(8558 + 13807) / 2 =
(22365) / 2 =
About 11182.5

But hey, we want a whole number, right?

Since we need to round to the nearest dollar, let's see which cent is closer: 11182.5 or 11183. Hmm, a tough decision indeed.

Ah, what the heck! Let's go with the nearest dollar. So, the poverty level cutoff in 1987 was approximately: 11,183 dollars.

Remember, this is just an approximation, which is the mathematical equivalent of close enough for government work!

To approximate the poverty level cutoff in 1987 using the midpoint formula, we need to find the midpoint between the income levels of 1980 and 1990.

The midpoint formula can be calculated using the following formula:
Midpoint = (Income of Year 1 + Income of Year 2) / 2

In this case, we will use the income levels of 1980 and 1990:

Income of 1980 = $8,558
Income of 1990 = $13,807

Now we can calculate the midpoint:
Midpoint = ($8,558 + $13,807) / 2 = $22,365.5

Therefore, the poverty level cutoff in 1987, using the midpoint formula, was approximately $22,365.5 dollars. Rounded to the nearest dollar, it would be $22,366 dollars.

8558+13807

--------------------- = 11182.5 ~ 11183
2

The answer is 11134.5, which would be rounded to 11135.

1987 is 7/10 of the way from 1980 to 1990

So, what is 7/10 of the way from 8558 to 13807 ?
