Reading tables 2

The table below shows the number of chickens sold by four friends from January to March. Except one entry is missing. What number should go in the empty cell?

So, let's see. This is the empty cell right over here they haven't filled out. How many? Let's see, this is chicken sold, so we don't know how many chickens Michael sold in March. But we know how many he sold in January and February. We also know the total he sold in the 3 months.

He sold a combined 4 plus 6; he sold 10 in January and February. He sold 10 in January and February, and we know he sold a total of 11. So this 11 is really the sum of these three right over here.

So this right over here in March has got to be one. He has got to have sold one chicken because we see 4 + 6 + 1 is 11. So let's check our answer. There we go!

Let's try this one. So here's the missing cell. Once again, we just need to look at the total. The total is 107, so these four numbers right over here, and one is missing, need to add up to be 107 for the solar panel installations in Wyoming.

So let's see, 32 + 27 is 59. 59 + 26 is, let's see, 79. It is 85. So these three add up to 85, but they're missing this one right over here.

So this is going to have to be whatever 107 is minus 85. So that is 22. 22 solar panels in Q3, because if 22 is here, 22 plus this, this, and this should be equal to 107.

So we're missing how many points Gabriella scores in the first quarter right over here. Once again, we know that she scores 35 points in the game in the other three quarters. She combines, she scores a combined—let's see, 10 plus 10 plus 8 is 28 points.

So she's 28 in the other three quarters, and she gets to 35. 3 plus 5 minus 28 is—she must have scored seven points in the first quarter. Seven points!

Let's do one more. So in Alabama, how many solar panel installations in the fourth quarter? See, 33 + 26 is 59; plus 21 is 80.

To get from 80 to 101, we need to get another 21 sold in the fourth quarter, and we got it right!
