Modeling with Equation/InequalityConstraints Practice Test

A rectangle is being designed for a poster. Let $L$ = length (in inches) and $W$ = width (in inches). The perimeter must be at most 40 inches, and the area must be at least 84 square inches. Also $L>0$ and $W>0$. Which system correctly represents these constraints?

A caterer is choosing trays of sandwiches and trays of fruit for an event. Let $x =$ number of sandwich trays and $y =$ number of fruit trays. Each sandwich tray serves 8 people and costs $\24$. Each fruit tray serves 6 people and costs $\18$. The caterer must serve at least 60 people and spend no more than $\180$. Trays must be whole numbers and nonnegative. Which constraint system matches the situation?
