At the beginning of the year, Juan had $20 in savings and saved an additional $17 each week thereafter. Nakeisha started the year with $100 and saved $9 every week. Let JJ represent the amount of money Juan has saved tt weeks after the beginning of the year and let NN represent the amount of money Nakeisha has saved tt weeks after the beginning of the year.
