a. four
b. three
c. two
d. five

The answer Is 3. I've taken the test.

Step-by-step explanation:

There are three basic categories of drivetrain systems: front-wheel drive systems, rear-wheel drive systems, and four-wheel drive systems. Each system is named according to the wheels that are driven by the engine.

we'll this would mean that the dunk tank and the bounce house are the same for 20 hours because the 2 represents that the two activities, and the 20 represents the amount of hours they both are. so with this said, it means that the answer is c. the costs for a dunk tank and bounce house are the same for 20 hours.

c.the costs for a dunk tank and bounce house are the same for 20 hours.

hope this .
