MF.QR.1 Standard MF-059-A10-V03

Identify relevant information, ignore distractors, and choose an appropriate operation or representation for a contextual problem.

Clean up a context into a useful model

Problem

\(\text{Five}~\text{teams}\) need \(18~\text{water}~\text{bottles}~\text{each}\), and each case holds \(12~\text{bottles}\); other details are irrelevant. Calculate total bottles \(B\), write the case-capacity inequality using \(c\), and give the least number of cases.

B = 18(5) = 90; 12c ≥ 90; least c = 7 cases

B = 18(5) = 90; 12c ≥ 90; least c = 8 cases

B = 12(5) = 60; 18c ≥ 60; least c = 4 cases

B = 18 + 5 = 23; 12c ≥ 23; least c = 2 cases
