How much money did Bob earn mowing lawns today if he earned $50 yesterday?

  1. $20

  2. $30

  3. $35

  4. $40

The correct answer is: $30

To determine how much Bob earned mowing lawns today based on the information given, we need to understand the context provided by his earnings of $50 yesterday. If Bob's earnings vary from day to day, it might indicate that he earned less today than yesterday. The selection of $30 as the earning for today suggests that there was a decrease in his earnings. This option could represent a realistic scenario where he might not have had as many clients today or charged differently for his services compared to yesterday. It's valuable to analyze daily earning patterns and factors influencing income, such as demand for lawn mowing services, competition with other lawn care providers, or personal circumstances affecting his ability to work as much. Other choices do not align with the concept of a decrease when compared to the $50 earned yesterday, making $30 a plausible figure for today's work.
