Can someone please help me with this question? Math isn't my strongest subject. For those who can't see the screen shot it says:
"Tatiana earns money by babysitting her little cousin. When she babysits for 2 hours she earns $27. When she babysits for 7 hours she earns $94.50. Which equation represents her total wages based on the hours that she works?"

y= 13.50 x

Step-by-step explanation:

x= time she worked

y= total wages

13.50= hourly rate

What we first need to do is to add up the amount she earned which is 94.50+27=121.5

We know that she worked a total of 9 hours so the equation is 121.5/9= 13.50

Thus we know the hourly pay to Tatiana and all we need to do is just multiply 13.50 by the hours she worked

y=13.50x

Step-by-step explanation:

94.50/7 = 13.5
