5. The number of feet that Jennifer can run in a given time period t is given by the expression 8t+2. Her
friend Erika can run a distance given by the expression 41 +3. Erika claims that she can only run half of
what Jennifer can plus an additional 2 feet. Is she correct?
(a) Let's build up some evidence by playing around with various values of t. Fill out the following chart for
both Jennifer and Erika's distances given the value of t.
