Anthony got a job babysitting each hour he works he will be paid eight dollars as a bonus. He will earn an additional $1.50 per hour for each child. He watches if his total hourly rate is $12.50. How many children does he watch? Write an equation in the form of PX plus Q equals R to represent the problem

Let's assume Anthony watches P children per hour.

For each child, he earns an additional $1.50, so the total amount earned from the children is 1.5P.
Since he also gets a bonus of $8 per hour, his total earnings per hour is 8 + 1.5P.
We know that the total hourly rate is $12.50, so we can set up the equation: 8 + 1.5P = 12.50.
To represent this equation in the form of PX plus Q equals R, we can rearrange it as follows:
1.5P + 8 = 12.50
1.5P = 12.50 - 8
1.5P = 4.50
P = 4.50 / 1.5
P = 3
Therefore, Anthony watches 3 children.
