The interest that Cindy earns on her investment is given by the equation l = 42t where t is the time in years that her money is invested. She makes a table to determine how much money she would earn for different values of t. She selects 5 as a value for t.
Substitute 5 to the t of the given equation for the interest, I = 42t. Substituting, I = 42 x (5) = 210 Therefore, the corresponding table entry for I in the same row as t = 5 is the value equal to 210.
