OpenStudy (mathstudent55):

Is there more to this problem before what your picture shows?

OpenStudy (khantahmina):

yeah i couldnt show it

OpenStudy (khantahmina):

OpenStudy (khantahmina):

@mathstudent55

OpenStudy (mathstudent55):

Part 1 is correct. Did you get part 2?

OpenStudy (khantahmina):

yeah t= hours after midnight

OpenStudy (mathstudent55):

Yes, t is hours after midnight, but part 2 asks specifically what t = 11 means. t = 11 means 11 hours after midnight, or 11 a.m. Your table is also correct.

OpenStudy (khantahmina):

yeah i have that just wrote it down. but thanks for clarifying

OpenStudy (mathstudent55):

Now part 3.

OpenStudy (mathstudent55):

One person every 30 seconds means 2 persons per minute.

OpenStudy (khantahmina):

can i set up a porportion

OpenStudy (mathstudent55):

You are asked how many cashiers are needed at 11:00 a.m. That is at t = 11

OpenStudy (mathstudent55):

Who do the cashiers deal with? People entering, people leaving, or both?

OpenStudy (khantahmina):

ppl entering so thats 918 ppl

OpenStudy (khantahmina):

2 customers per minute n theres 60 mintues in 11am.

OpenStudy (mathstudent55):

Correct.

OpenStudy (mathstudent55):

What class is this, btw?

OpenStudy (khantahmina):

2/60 = 918/x ?

OpenStudy (khantahmina):

summer hw for beginning ap calculus. i took pre calculus and then now im in ap calculus

OpenStudy (khantahmina):

u there @mathstudent55

OpenStudy (mathstudent55):

Yes, I'm thinking about it. Cashiers have to deal with 918 people entering at 11 a.m. Notice that at t = 13, or 1 p.m., there are also 918 people entering. From 11 a.m. to 1 p.m., the number of people entering will increase until noon, and then will begin decreasing so that by 1 p.m. it is 918 again. 918 is the instantaneous value of E(t) at t = 11. I don't understand how we know how much time we have to deal with these 918 people to figure out how many cashiers we need given that they deal with a person every 30 seconds. Do all of these 918 people have to be dealt with at once?

OpenStudy (khantahmina):

well... it states: Cashiers can serve an averge of one person every 30 sec. at this rate how many cashiers should be in duty at the parks entrance at 11am. show the calculations that support your answer

OpenStudy (khantahmina):

all 918 ppl at once i think so bc it doesnt specify anything else

OpenStudy (mathstudent55):

Sorry, I don't know.

OpenStudy (khantahmina):

ok can u help me with the next question then
