Question

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.

GPT 3.5 · Answer

Let x be the number of children Anthony watches.
Anthony earns $8 per hour + $1.50 per child per hour = $8x + $1.50x = $9.50x for each hour he works.
To find the total hourly rate, add the $9.50x to the base rate of $8.00 per hour: $9.50x + $8.00 = $12.50.
Subtracting $8.00 from both sides of the equation gives $9.50x = $4.50.
Dividing both sides of the equation by $9.50 gives x = 4.5/$9.50 children.
Therefore, Anthony is watching 4.5/$9.50 = 0.47 children. Answer: \boxed{0}.
