Help on algebra problem?
Bob is paid after he finishes walking his customers dogs.
-He is paid $26 after two hours of work.
-He is paid $6.50 each additional hour (n) beyond the first two hours.
The function f(n) represents the amount of money Bob earns each day he walks dogs. If f(n) is at least $30, create an expression that defines the value of n.
So basically just how much time would it take for Bob to make $30 is what I need to know, I know it would be 2 hours, I just don't know how many minutes.
Thanks!

If f(n) is at least $30, then the expression would be f(n) = 26 + 2.5x (x being the number of hours worked beyond the first two). To find out how much time he worked, set your equation equal to $30 to figure out how many hours he worked after the initial two hours, so your equation is 2.5x + 26 = 30, then subtract 26 from both sides and divide both sides by 2.5, and you'll get x = 1.6. Now since this is the time that he worked after, you have to add in the initial two hours, meaning he worked a total of 3.6 hours to earn $30. In minutes, 0.6 hours is equal to 60/100 of an hour, which is 60 minutes. you can simplify 60/100 to 3/5, so take 3/5 x 60 minutes, and you get 36 minutes. So in total, Bob worked 3 hours and 36 minutes in order to make $30. I hope this helped!
