The rest are all fixed values. 27 points. 80 miles per hour. half the speed of the car.

Answer 2

The correct answers are:

A) the number of different colors on the page; and 
D) half the speed of the car.

Explanation:

A variable represents an unknown amount.  

For A, we do not know how many colors are on the page; this means we would use a variable to represent it.

For D, while we know we want half of the speed of the car, we do not know what the speed of the car actually is; therefore we would use a variable to represent it.
