Anthony got a job babysitting. Each hour he works he will be paid $8.00. 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 px+q=r to represent this problem

Answer 1

Let "x" be the number of children Anthony watches.
The total amount he earns for watching children is $1.50x.
The amount he earns without watching any children is $8.00.
Therefore, his total hourly rate is $8.00 + $1.50x = $12.50.
Subtracting $8.00 from both sides of the equation, we get $1.50x = $12.50 - $8.00 which is $1.50x = $4.50.
Dividing both sides by $1.50, we get x = 3.
He watches 3 children.
Therefore, the equation in the form px+q=r is 1.50x + 8 = 12.50.
