To evaluate S(t) when t = 4, we plug in t = 4 into the equation:
S(4) = (5-4)(2(4)-6) + 50S(4) = (1)(8-6) + 50S(4) = (1)(2) + 50S(4) = 2 + 50S(4) = 52
Therefore, when t = 4, S(t) = 52.
To evaluate S(t) when t = 4, we plug in t = 4 into the equation:
S(4) = (5-4)(2(4)-6) + 50
S(4) = (1)(8-6) + 50
S(4) = (1)(2) + 50
S(4) = 2 + 50
S(4) = 52
Therefore, when t = 4, S(t) = 52.
