The amount of money a worker makes varies directly with the hourly rate of pay. Worker A earns $168 for an 8-hour period. Worker B earns the same hourly rate as Worker A but works for only 6 hours. What does Worker B earn?

Worker A earns $168 for an 8-hour period, so their hourly rate of pay is $168/8 = $<<168/8=21>>21 per hour.

Worker B also earns $21 per hour.

If Worker B works for 6 hours, then they will earn 6 * $21 = $<<6*21=126>>126 in total. Answer: \boxed{126}.

To find out what Worker B earns, we can set up a proportion based on the given information:

Worker A earns $168 for an 8-hour period, so the rate would be $168/8 = $21 per hour.

Therefore, Worker B, who works for 6 hours, would earn 6 hours * $21 per hour = $<<6*21=126>>126.

Worker B would earn $126.

To find out how much Worker B earns, we can use the concept of direct variation. Direct variation means that when one quantity increases, the other quantity increases proportionally.

In this case, we are given that the amount of money a worker earns varies directly with the hourly rate. Therefore, we can set up a proportion to solve for Worker B's earnings.

Let's denote the hourly rate as "r" (which is the same for both workers) and Worker B's earnings as "E".

According to the given information:
Worker A earns $168 for an 8-hour period, which can be represented as:
Worker A's earnings = 8 hours * hourly rate = 8r

We are also given that Worker B has the same hourly rate as Worker A but works for only 6 hours:
Worker B's earnings = 6 hours * hourly rate = 6r

Since Worker A earns $168, we can set up the following proportion:
8r / 168 = 6r / E

To solve for Worker B's earnings, we can cross-multiply and solve for E:

8r * E = 168 * 6r
8E = 1008
E = 1008 / 8
E = $126

Therefore, Worker B earns $126.
