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 sintering department?
A)B/15 + C/10 + D/10 = 330
B)B/30 + C/20 + D/20 = 330
C)A/70 + B/50 + C/50 + D/44 ≥ 330
D)A/35 + B/25 + C/25 + D/22 ≤ 330

The correct inequality describes the maximum time constraint of the sintering department, where the sum of the time each product (A, B, C, D) spends in the department, based on their respective processing times, should not exceed 330 hours.
