At the beginning of the year, Evelyn had $30 in savings and saved an additional $12 each week thereafter. Cooper started the year with $75 and saved $7 every week. Let EE represent the amount of money Evelyn has saved tt weeks after the beginning of the year and let CC represent the amount of money Cooper has saved tt weeks after the beginning of the year. Write an equation for each situation, in terms of t, t, and determine the interval of time when Evelyn has more in savings than Cooper.
