Question

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, rrr, if she has already scored ppp points.

Answer 1

The most points Sidney has scored in a basketball game is 28.

She is trying to tie that record in her current game.

Let r be the number of points needs to score

p  is the points she scored already

Total record in basket ball game = 28

points needs to score + scored already = total record

So equation becomes p + r = 28

Subtract p on both sides

So number of points needs to score r= 28 - p

Answer 2

To find out how many more points Sidney needs to score to tie her record, r, you can use the equation r = 28 − p.  For example, when p = 10, you can subtract r = 28 − 10So, when p = 10, then r = 18.
