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?

Question

Write an equation in the form px+q=r to represent this problem.

Answer 1

Let's assume that Anthony is watching x number of children.

According to the problem, Anthony will be paid $8.00 per hour, and he will earn an additional $1.50 per hour for each child he watches. Therefore, the amount he earns per hour for watching children will be x * $1.50.

So, his total hourly rate will be $8.00 + x * $1.50.

According to the problem, his total hourly rate is $12.50.

Hence, we can write the equation in the form px + q = r as follows:
$8.00 + x * $1.50 = $12.50

Simplifying the equation, we get:
8 + 1.5x = 12.5

Subtracting 8 from both sides, we get:
1.5x = 4.5

Dividing both sides by 1.5, we get:
x = 3

Therefore, Anthony watches 3 children.
