Linda made $104 for 8 hours of work. At the same rate, how many hours would she have to work to make $143?

11 hours

Step-by-step explanation:

104 dollars for 8 hours of work. So how much money per hour?

104/8= 13 dollars per hour

At the same rate = 13 dollars per hour, so

How many hours to make 143 dollars? With the same rate?

143/13 = 11 hours

Linda would have to work for 11 hours to make $143.

Step-by-step explanation:

First, let's figure out how much she earns per hour, then we can figure out how much she would have to work to make $143.  

Equation: 104/8 = 13

Linda earns $13 per hour.

Then to find how many hours she would have to work to make $143, divide the money with how many she earns per hour.

Equation: 143/13 = 11

Conclusion: Linda would have to work for 11 hours to make $143.
