To determine the number of children Anthony watches, we can set up an equation based on the information given.
Let \( x \) represent the number of children Anthony watches.
His total hourly pay can be expressed as:
\[ \text{Total Pay} = \text{Base Pay} + \text{Bonus} \]
The base pay is $8.00 per hour, and the bonus is $1.50 per hour for each child, so the bonus will be \( 1.50x \).
Thus, the total pay can be written as:
\[ 8.00 + 1.50x \]
According to the problem, the total hourly rate is $12.50. We will set this expression equal to $12.50:
\[ 8.00 + 1.50x = 12.50 \]
Now, we will rearrange this equation to match the form \( px + q = r \):
\[ 1.50x + 8.00 = 12.50 \]
This equation is now in the form:
- \( p = 1.50 \)
- \( q = 8.00 \)
- \( r = 12.50 \)
So the final equation representing the problem is:
\[ 1.50x + 8.00 = 12.50 \]
