Is the answer is c can you show me how to do it anyone

the answer is C.

The way you would do it is first write out what you know about the equation

x= money per hour     11= hours worked       71.50= money made

then you think about what the question is asking, in this it is asking for the formula not the answer. So you would then write out another equation

11x= hours x money per hour

So to find out how much Raquel earns per hour you would write out the equation

11x= 71.50      (because the equation translates to 11 times the amount per hour equals the total amount of money made
