OpenStudy (anonymous):

:P

OpenStudy (caroline1218):

@Juliusmattos12 You think it is D?

OpenStudy (anonymous):

yes

OpenStudy (caroline1218):

How did you get D?

OpenStudy (caroline1218):

@jhonyy9 @imqwerty @nincompoop @mathmale @pooja195

OpenStudy (xapproachesinfinity):

break even ha what is the equation you established from this load of words?

OpenStudy (xapproachesinfinity):

have you got one yet?

OpenStudy (caroline1218):

My equation was 1,300 + (10t - 3) = 1,800 + 1,500

OpenStudy (xapproachesinfinity):

hm denote the profit F and number of ticket n F(n)=10n-3n-1800-1500

OpenStudy (xapproachesinfinity):

why is this equation right or wrong?

OpenStudy (caroline1218):

What do you mean?

OpenStudy (xapproachesinfinity):

this equation is just wrote do you thing I'm right or wrong?

OpenStudy (caroline1218):

Um, I'm not sure. I thought the equation I wrote was ok, but now idk.

OpenStudy (xapproachesinfinity):

hhhh your equation seemed somewhat good but there is something messing

OpenStudy (xapproachesinfinity):

missing*

OpenStudy (xapproachesinfinity):

at any rate, -3n because of each ticket sold we give free hat the number of hats depend on the number of fans which tells us number of tickets sold

OpenStudy (xapproachesinfinity):

naturally 10n is the what you make not including what you pay for players and worker and the cost of all free hats

OpenStudy (xapproachesinfinity):

so makes sense that the actual profit is 10n-3n-1800-1500

OpenStudy (xapproachesinfinity):

this is a general equation for the situation

OpenStudy (xapproachesinfinity):

break even is when total cost equal profit

OpenStudy (caroline1218):

Ok

OpenStudy (xapproachesinfinity):

the profit we desire is 1300 so we have to solve this equation 1300=7n-1800-1500

OpenStudy (caroline1218):

When using that equation I got 657.143??

OpenStudy (xapproachesinfinity):

if i don't make sense disregard this hehehe

OpenStudy (xapproachesinfinity):

so n=657 no decimal round this is real life problem

OpenStudy (xapproachesinfinity):

we say roughly 657 tickets to break even

OpenStudy (caroline1218):

But that's not one of the answer options.

OpenStudy (xapproachesinfinity):

so what are the options

OpenStudy (xapproachesinfinity):

oh i see the options

OpenStudy (mathstudent55):

Let t = number of tickets Revenue: 10t + 1300 Expenses: 1800 + 1500 + 3t Break even when revenue = expenses 10t + 1300 = 1800 + 1500 + 3t 7t = 2000 t = 2000/7 = 286

OpenStudy (xapproachesinfinity):

i see where i missed

OpenStudy (xapproachesinfinity):

286 is the exact number of tickets to break even

OpenStudy (xapproachesinfinity):

based on that you need to figure out the smallest number of tickets to break even
