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 = 86.5t + 342, 0 ≤ t ≤ 13 Williams-Sonoma: W = −2.92t²
+ 52.0t + 381, 0 ≤ t ≤ 13

99. Solve the inequality B(t) ≥ 900. Explain what the solution of the inequality represents.

100. Solve the inequality W(t) ≤ 600. Explain what the solution of the inequality represents.

101. Solve the equation B(t) = W(t). Explain what the solution of the equation represents.

102. Solve the inequality B(t) ≥ W(t). Explain what the solution of the inequality represents
