8-99.

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

 Days at New Job Money in Account $0$ $27$ $1$ $70$ $2$ $113$ $3$ $156$

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.

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

$y = 43x + 27$

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

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