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.

To solve this problem, we need to set up an equation using the given information. Let's break down the problem:

Anthony is paid $8.00 per hour for his work, and in addition to that, he earns an extra $1.50 per hour for each child he watches. So, the amount he earns for each hour can be represented as $8.00 + ($1.50 x number of children he watches).

If his total hourly rate is $12.50, we can set up the equation:

$8.00 + ($1.50 x number of children) = $12.50.

In this equation, the "number of children" is the variable we need to solve for.

Now, let's write this equation in the form px + q = r:

1.50x + 8.00 = 12.50,

Where:
p = 1.50 (the rate for each child)
x = number of children
q = 8.00 (the base rate for Anthony)
r = 12.50 (the total hourly rate)

So, the equation in the form px + q = r representing this problem is 1.50x + 8.00 = 12.50.

Let x be the number of children Anthony watches.

The equation to represent this problem is:
$8.00 + $1.50x = $12.50

Susan read 17 pages today. That is 8 pages fewer than 1/3 of the pages she read yesterday. How many pages did she read yesterday?

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.
