Q. Ms. Yamada runs the school cafeteria. In October, she had to order 1515 cases of chocolate milk twice because the students at her school love it so much. Each case contains cc cartons of chocolate milk.\newlinePick all the expressions that represent how many cartons of chocolate milk Ms. Yamada ordered in October.\newlineMulti-select Choices:\newline(A) 2c+15c2c + 15c\newline(B) 2(15c)2(15c)\newline(C) 30c30c\newline(D) c(2+15)c(2 + 15)
  1. Calculate cases ordered: Calculate the total number of cases ordered in October.\newlineMs. Yamada ordered 1515 cases twice, so:\newline1515 cases ×2=30\times 2 = 30 cases
  2. Determine total cartons: Determine the total number of cartons ordered. Each case contains cc cartons, so for 3030 cases: 3030 cases ×c\times c cartons/case =30c= 30c cartons
  3. Match total cartons expression: Match the expression that represents the total number of cartons.\newlineFrom the choices given:\newline(A) 2c+15c=17c2c + 15c = 17c (Incorrect, doesn't match 30c30c)\newline(B) 2(15c)=30c2(15c) = 30c (Correct, matches the calculation)\newline(C) 30c30c (Correct, directly matches the calculation)\newline(D) c(2+15)=17cc(2 + 15) = 17c (Incorrect, doesn't match 30c30c)
