At the beginning of the year, Josue had $70 in savings and saved an additional $9
each week thereafter. Arianna started the year with $30 and saved $19 every week.
Let J represent the amount of money Josue has saved t weeks after the beginning of
the year and let A represent the amount of money Arianna has saved t weeks after
the beginning of the year. Write an equation for each situation, in terms of t, and
determine the interval of time when Josue has more in savings than Arianna.
