answer:
To compare the babysitting charges between Bobby and Suzie, let's break down the cost calculations for each:
1. Bobby charges $10 per hour, so the total cost for babysitting would be calculated by multiplying the number of hours by $10.
2. Suzie charges $5 per hour plus a $20 fee. In this case, we need to consider both the hourly rate and the additional fee. Let's assume the number of hours is represented by "h".
- The cost for the hourly rate would be calculated by multiplying the number of hours by $5: 5h.
- In addition to the hourly rate, Suzie charges a $20 fee: $20.
3. Now, let's compare the total cost for both Bobby and Suzie. We can set up an equation to represent this:
Total cost for Bobby = Total cost for Suzie
10h = 5h + 20
4. To solve the equation, we can subtract 5h from both sides to isolate the variable:
10h - 5h = 5h - 5h + 20
5h = 20
5. Finally, we can divide both sides of the equation by 5 to find the value of "h":
h = 4
Therefore, if the number of hours is 4, Bobby and Suzie would charge the same total amount for babysitting. Bobby would charge $40 (10 * 4), and Suzie would charge $40 (5 * 4 + 20).
