The most points Sidney has scored in a basketball game is 28. She is trying to tie that record in her current game. Write an equation for the number of points Sidney needs to score to tie her record, r, if she has already scored p points.

r = 28 - p

p       r

10    18

12    16

14    14

16    12

Step-by-step explanation:

We have the highest number of points Sidney has scored in a basketball game is 28.

We have to "r" the number of points that he needs to score and "p" are the points that he has already scored and the sum of these would be 28, that is, the total record.

So the equation would be

p + r = 28

we solve for "r" and we are left with:

r = 28 - p

Now, to fill the table it is missing when p = 14 and when p = 16

r = 28 - 14 = 14

r = 28 - 16 = 12

Therefore the complete table would be:

p       r

10    18

12    16

14    14

16    12
