For each hour he babysits , anderson earns $1 more than half of carey's hourly rate. anderson earns $6 per hour. which equation can be solved for carey's hourly rate, c?

The answer would be: 

C=12x-1

x being the amount of hours Carey is working.

c being the amount she is getting paid. 

The reason why it is 12 is because Anderson is only getting paid $6 per hour, which is half minus 1 per hour Carey is getting paid. 

So, by doubling the amount of what Anderson is getting paid minus 1, multiplied by the amount of hours she is working, you should get the correct answer. 

6 - 1 = 5 and then 5 times 2 is 10 . So $10 is Carey's hourly rate.
So to do it backwards would be Anderson earns $1 more than half of Carey's hourly rate. Carey's hourly rate is $10 so 10 divided by two is 5 and 5+1= 6.
