Answer:

The correct answer is:

  • 30 = 10 + 3(h - 2)

        30 = 10 + 3h - 6

        26 = 3h

        h = 8.67

Step-by-step explanation:

We're gonna calculate by our part the hours a new costumer can rent a bike and pay a total of $30, using the original function:

  • f (h) = 10 + 3(h - 2)

Where:

  • f (h) = Total cost.
  • h = the number of hours.

We know The total money spent must be $30, by this reason, the function change to:

  • 30 = 10 + 3(h - 2)

Now, we must clear the h variable, by this reason, we multiply 3 by h and 2:

  • 30 = 10 + 3*h - 3*2
  • 30 = 10 + 3h - 6

We pass the 10 and the -6 to the left side of the equality:

  • 30 - 10 + 6 = 3h (Remember to change the signs when you do this step)
  • 26 = 3h

Finally, we pass the 3 to the left side of the equality:

26 / 3 = h (the 3 pass to divide because is multiplying the x)

  • 8.666666666667 = h

If we just use two decimals, the number of hours is:

  • h = 8.67

How the third option is the one that shows this calculation and result, that is the correct answer.
