Question

Two work crews earn money depending on how many hours they work, as shown in the graph and table below.

Write the equation that represents the data set for Crew A using the variables E for earnings and h for hours.
Write the equation that represents the data set for Crew B using the variables E for earnings and h for hours.

Answer 1

To represent the data set for Crew A, the equation is E = kh, and for Crew B, the equation is E = mh.

Step-by-step explanation:

In order to write the equation that represents the data set for Crew A, we need to examine the graph or table provided. Let's assume that for Crew A, the earnings (E) are directly proportional to the number of hours worked (h).

This means that if h increases, E will also increase. We can write the equation as:

E = kh

To determine the value of k, we can use the graph or table. Once we have the value of k, we can substitute it back into the equation to get the final equation for Crew A.

Similarly, we can write the equation for Crew B as:

E = mh

Again, we need to find the value of m using the provided information and substitute it back into the equation.
