Ali made $126 for 9 hours of work. At the same rate, how many hours would he have to work to make $168 ?

12 hours

Step-by-step explanation:

First to solve this problem, let's look at what we are dealing with here. It says that Ali made $126 for 9 hours of work.

Let's set that up into a fraction so it's easier to look at.

money/time = 126/9

Now that we have that set up let's look at our other piece of information.

It asks for how many hours would Ali have to work in order to make $168 so let's figure that out.

In order to find out the number of hours, let's first find our unit rate which can be simply found by dividing our given money/time.

126/9 = 14.

This means that for every 1 hour, there will be 14 dollars earned.

Now that we know that, let's look for how many hours it take to earn $168.

In order to do that simply see how many times 14 goes into 168 (division) and that way you can see how many hours it will take to earn $168.

168/14 = 12 hours.

12 servings. 4 times 3= 12
