In Exercises 99–102, use the models below, which approximate the numbers of Bed Bath & Beyond stores B and Williams-Sonoma stores W for the years 2000 through 2013, where t is the year, with t = 0 corresponding to 2000. (Sources: Bed Bath & Beyond, Inc.; Williams-Sonoma, Inc.)
Bed bath & Beyond:
\(B=86.5 t-342,\ \ \ \ \ \ \ 0 \leq t \leq 13\)
Williams-Sonoma:
\(W=-2.92 t^{2}+52.0 t+381,\ \ \ \ \ 0 \leq t \leq 13\)
Solve the inequality \(B(t) \geq 900\). Explain what the solution of the inequality represents.
