Answer:

C.  Add 15 to both sides

Step-by-step explanation:

Given equation:

99x – 15 = 45

To solve:

<u>Step 1</u>:  Add 15 to both sides:

⇒ 99x – 15 + 15 = 45 + 15

⇒ 99x = 60

<u>Step 2</u>:  Divide both sides by 99:

⇒ 99x ÷ 99 = 60 ÷ 99

⇒ x = 60/99

⇒ x = 20/33

Step-by-step explanation:

Let the amount charged is y and number of hours is x.

Then the equations are as below.

  • y = 150x + 250

<u>Attorney B:</u>

  • y = 175x + 150

<u>If the amounts are equal, then:</u>

  • 150x + 250 = 175x + 150
  • 175x - 150x = 250 - 150
  • 25x = 100
  • x = 4 hours
