Question

Which equation can be used to describe the direct variation function between E, the total earnings in dollars, and h, the number of hours worked? E = 1.5h E = 7.5h E = 13h E = 15h

Answer 1

The answer is E=7.5h hope it helps

Answer 2

Let us take a sharp point for the graph.

In 4 hours total earning is $30.

Therefore, earnings per hours would be 30/4 = $7.5 per hour.

Are given direct variation between Total earnings(E) and Number of hours worked(h).

So, we can setup a direct variation as

Total earnings = Earning each hour * Number of hours.

Therefore, direct variation function would be

E=7.5*h.

Therefore, the direct variation function between E, the total earnings in dollars, and h, the number of hours worked is E = 7.5h.
