Question

Mariana wears her winter coat when the temperature is colder than −4°C. If t is the temperature, in °C , at which Mariana wears her winter coat, which of the following inequalities best models the situation?    (A) t (B) t>−4 (C) t<4 (D) t≥4

Understand the problem: Understand the problem. Mariana wears her winter coat when the temperature is colder than −4°C. We need to find an inequality that represents temperatures colder than −4°C.Translate the situation: Translate the situation into an inequality. The phrase ＂colder than −4°C＂ means that the temperature is less than −4°C. Therefore, the inequality should show that the temperature t is less than −4.Identify the correct inequality: Identify the correct inequality from the given options. (A) t = −4 is incorrect because it represents a temperature exactly at −4°C, not colder. (B) t > −4 is incorrect because it represents temperatures warmer than −4°C. (C) t < 4 is incorrect because it does not specify that the temperature is below zero, which is necessary for temperatures colder than −4°C. (D) t ≥ 4 is incorrect because it represents temperatures that are 4°C or warmer. The correct inequality is not listed explicitly, but we can infer that the intended correct option should be t < −4, which is not present among the options.
