The equation you are looking for is $100 + $50x = $150 + $30x.
To find this equation, you simply write the parts as stated in the information above ($100 plus $50 per hour & $150 plus $30 per hour) and add a variable to account for the hours (which in this case, is "x").
Now, if you were to solve, you would simply fill in the "x" value with numbers (preferably starting at 1) and solve each side until they equal each other.
I hope this helps!
