Question

A mail distribution center processes as many as 150,000 pieces of mail each day. The mail is sent via ground and air. Each land carrier takes 1800 pieces per load and each air carrier 1500 pieces per load. The loading equipment is able to handle as many as 150 loads per day. Let x be the number of loads by land carriers and y the number of loads by air carriers. Which system of inequalities represents this situation? Click on the correct answer. 1500x + 1800y ≥ 150,000 x + y ≤ 150 1800x + 1500y ≤ 150,000 x + y ≤ 150 1800x + 1500y ≥ 150,000 x + y ≥ 150 1500x + 1800y ≤ 150,000 x + y ≤ 150

Answer 1

x = land carriers = 1800x

y = air carries = 1500y

 as many as means up to that amount so <=150000 and <= 150

so equation is:

1800x + 1500y ≤ 150,000 x + y ≤ 150
