Ghella [55]

Answer:The value of the expression increases as r decreases.

Step-by-step explanation:

To find : What happens to the value of the expression as r decreases?

Given Expression: 80-2r

We check for different value of r as decreasing order,

r        80-2r

5        80-10=70

4        80-8=72

3        80-6=74

2        80-4=76

1         80-2=78

As r decreases the value of expression increases.

Therefore, the value of the expression increases as r decreases.

Hope this helps!
