Multiple Choice

Use the case below to answer the following question(s) .
S&N Manufacturing makes four different steel sheets,A,B,C,and D,with different percentages of iron.Each sheet must flow through five departments,forming,rolling,sintering,painting,and quality check.The table below shows the relevant data.Production rates are shown in units/hour.(Sheet A uses imported steel and does not require rolling.) S&N wants to determine the number of steel sheets to produce in order to maximize monthly profit.
Let A,B,C,and D denote the number of units of model A,B,C,and D to be produced,respectively.
-Which of the following is the inequality/equality that describes the time constraint of the painting department?

• A)A/30 + B/30 + C/35 + D/25 ≤ 330
• B)B/30 + C/20 + D/20 = 330
• C)A/70 + B/50 + C/50 + D/44 = 330
• D)A/60 + B/60 + C/70 + D/50 ≤ 330
