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

1,407.5 hours

step-by-step explanation:

we first convert all the time to hours and then sum them up.

there are 24 hours in 1 day, in 58 days, there are 24 x 58 = 1,392 hours.

there are 60 minutes in 1 hour, thus, 30 minutes will be equivalent to 30 / 60 = 0.5 hours.

therefore, the number of hours it will take mercury to complete a full rotation is 1,392 + 15 + 0.5 = 1,407.5 hours

i think its a.

hope this
