Anthony got A job babysitting. Each hour he works he will paid $8.00. As A bonus, he will earn an additional $1.50 per hour for each child. If his total hourly rate is $12.50, how many children does he watch. Use px+q=r

Let the number of children Anthony watches be x.

The total hourly rate is given by the equation 8 + 1.50x = 12.50.
Simplifying the equation, we get 1.50x = 12.50 - 8 = 4.50.
Dividing both sides by 1.50, we get x = 4.50 / 1.50 = <<4.50/1.50=3>>3.
Therefore, Anthony watches 3 children.
