To solve this problem, we need to set up an equation using the given information.
Let's assume the number of children Anthony watches is represented by the variable 'x'.
According to the information given, Anthony receives a base pay of $8.00 per hour and an additional $1.50 per hour for each child he watches. Therefore, the amount Anthony earns in an hour can be calculated as follows:
Base Pay + (Extra Pay per Child * Number of Children)
Base Pay = $8.00
Extra Pay per Child = $1.50
The total hourly rate Anthony receives is $12.50. So, we can set up the equation:
$8.00 + ($1.50 * x) = $12.50
Now, we can simplify the equation to find the value of 'x', representing the number of children Anthony watches.
$8.00 + $1.50x = $12.50
Subtract $8.00 from both sides to isolate the term with 'x':
$1.50x = $12.50 - $8.00
$1.50x = $4.50
To solve for 'x', divide both sides by $1.50:
x = $4.50 / $1.50
x = 3
So, Anthony watches 3 children.
The equation in the requested form, px + q = r, would be:
$1.50x + $8.00 = $12.50
