Question

You earn $7.50 per hour to help your uncle in his shop. You earn $33.75. Write and solve an equation to find how may hours you worked.

Answer 1

Answer:

x = 4.5

Step-by-step explanation:

Let's begin by writing the equation in words to express the worker's earnings:

   Rate x Time = Earnings

 

Now let's rewrite this equation replacing the words with our given numerical facts and our unknown (x):

 

   Rate x Time = Earnings  

 

   Rate = $7.50 per hour

   Time = x (# hours worked)

   Earnings = 33.75

 

   (7.50)(x) = 33.75

 

Finally, we'll solve our equation for our unknown (x):

   (7.50)(x) = 33.75

   7.50x = 33.75

         x = 33.75/7.50

         x = 4.5 (# hours worked)
