Timmy gets paid $for every hour he works plus $9 a day for his paper route. If he made $24 yesterday, how many hours did he work? show the work.

Let X= hours worked. Since we don’t know the hours worked and how much he gets paid all we can do is

X+9 = 24
X=15 but this is not the hours worked unless he got paid per 1$ per hour
If we knew the hours it would be
X= 24/$per hour
