Wanda sews small and large gloves. It takes her 45 minutes to sew a small pair of gloves and 120 minutes to sew a large pair of gloves. The costs of producing the gloves are $2 for a small pair and $4 for a large pair. Wanda has 16 hours available to sew gloves. The materials to make the gloves cost at most $40. The system of linear inequalites below represents the situation.

What does the solution (16, 2) represent?

Wanda cose guantes grandes y pequeños. Le toma 45 minutos coser un par de guantes pequeños y 120 minutos coser un par de guantes grandes. Los costos de producción de los guantes son $2 por un par pequeño y $4 por un par grande. Wanda tiene 16 horas disponibles para coser guantes. Los materiales para fabricar los guantes cuestan como máximo 40 dólares. El siguiente sistema de desigualdades lineales representa la situación.

¿Qué representa la solución (16, 2)?

 The solution (16, 2) is the point where the boundary lines of the system of inequalities intersect. Wanda can make 16 pairs of small gloves and 2 pairs of large gloves in 16 hours and remain at a cost of $40.

La solución (16, 2) es el punto donde se cruzan las líneas límite del sistema de desigualdades. Wanda puede fabricar 16 pares de guantes pequeños y 2 pares de guantes grandes en 16 horas y hacerlo a un costo de $40.

Hiro and Sofia purchased shirts and pants from a store. The price of each shirt purchased was the same and the price each pair of pants was the same. Hiro purchased 4 shirts and 2 pairs of pants for $86. Sofia purchased 3 shirts and 5 pairs of pants for $166. Which of the folowing systems of equations this situation, if x represents the price, in dollars, of each shirt and y represents the price, in dollars, of each pair of pants?

Hiro y Sofia compraron camisas y pantalones en una tienda. El precio de cada camisa comprada era el mismo y el precio de cada par de pantalones era el mismo. Hiro compró 4 camisas y 2 pares de pantalones por $86. Sofía compró 3 camisas y 5 pares de pantalones por $166. ¿Cuál de los siguientes sistemas de ecuaciones representa esta situación, si x representa el precio, en dólares, de cada camisa e y representa el precio, en dólares, de cada par de pantalones?
