What happens to the value of the expression 80-2r80−2r80, minus, 2, r as rrr decreases? Choose 1 Choose 1 (Choice A) A It increases. (Choice B) B It decreases. (Choice C) C It stays the same. Stuck?Watch a video or use a hint.

(Choice B) B It decreases.

Step-by-step explanation:

According to the situation, the solution of the value of the expression is as follows

Let us assume

r         80 -2r

5        80 - 10 = 70

4        80 - 8 = 72

3        80 - 6 = 74

2        80 - 4 = 76

1         80 - 2 = 78

As we can from the above calculation that expression value risen if r value decreased

Therefore the correct option is B.
