Answer 2

B. how many times Lexi mowed the lawn in June

Step-by-step explanation:

• Total amount of money she has is 9x−5

Here given she receives the same amount of money for every time she mows the lawn.

In Option A, its wrong as she spent 5 dollars on fuel.

In option B, its correct as it refers the times she mowed and got paid for mowing.

In option C, here we can see "each time" which is wrong, here it refers to total 9 weeks.

In option D, the total amount of money she earns : 9x−5 . not what 9 refers to in this equation.
