At the beginning of the year, Rajani had $50 in savings and saved an additional $15 each week
thereafter. Charlotte started the year with $95 and saved $10 every week. Let R represent the amount
of money Rajani has saved t weeks after the beginning of the year and let C represent the amount of
money Charlotte 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 Rajani has more in savings than
Charlotte.
