A restaurant from which Yasmine often buys the lunches charges \( \$ 7 \) for a cold dish and \( \$ 11 \) for a hot dish, including drinks. If each meal is subject to a \( 5.75 \% \) sales tax, which of the following inequali- ties represents the number of cold dishes (c) and hot dishes \( (h) \) that Yasmine can purchase for sales-related lunches in one week, assuming she purchases all the lunches from this restaurant? A) \( 7 c+11 h \leq 1.0575(300) \) B) \( 7 c+11 h \geq 1.0575(300) \) C) \( 1.0575(7 c+11 h) \leq 300 \) D) \( 1.0575(7 c+11 h) \geq 300 \)
