The table below shows the amount of money Francis had in his bank account each day since he started his new job.

1. Write a rule for the amount of money in Francis’s account. Let $x$ represent the number of days and $y$ represent the number of dollars in the account.

   Hint (a):

   Look at the chart and see if you can determine a pattern.

   Answer (a):

   $y = 43x + 27$

2. When will Francis have more than $$1000$ in his account?

   Hint (b):

   Set $y = 1000$ and then solve the equation for $x$.
   $y = 43x + 27$
