To find the equation that represents the total charge for babysitting, we need to account for both the base fee and the hourly rate.
Maria charges a $10 base fee and $15 per hour for babysitting. If she is going to charge a total of $160, we can set up the equation as follows:
- Start with the base fee: $10
- For each hour of babysitting, she charges $15, which is represented by \(15h\), where \(h\) is the number of hours.
Thus, the total charge can be represented as:
\[ \text{Total charge} = \text{Base fee} + \text{Hourly charge} \]
This can be organized into the equation:
\[ 10 + 15h = 160 \]
Now, let's look at the provided responses:
- A \( 15h - 10 = 160 \)
- B \( 10h + 15 = 160 \)
- C \( (10 + 15)h = 160 \)
- D \( 10 + 15h = 160 \)
The correct equation is:
D \( 10 + 15h = 160 \)
