The total amount the Noah receives will be equal to his hourly payment multiplied by the number of working of hours added to the 500$ bonus which he received.
Now, Noah get 28$ per hour and he works for x hours. This means that the payment he gets for working = 28x Then, we will add the $500 which he received as a bonus. Doing this, we can get the expression that models his total payment as follows: y = 28x + 500
