Hello Everyone!

I can't seem to find the right answer to the following case question:

World Cinema is going to make an investment of $255 000 to open 3 new cinema rooms. 30% of the total investment will go to marketing costs, which equals three-fourths of the construction costs. The remaining amount goes to operation costs of the 3 cinema rooms in 1 year. How much does it cost to operate 1 cinema room in a month?

After calculation, I find Marketing Costs (76 500$), Construction Costs (102 000$) and Total Operation Costs for 3 cinema rooms in a year (76 500$) so Operation Costs for 1 cinema room in a month (2 125$).

Does someone know why is the solution supposed to be 2 550$?

Thanks in advance for your insights!

Agree with you and Vlad on the result. The given solution seems flawed.

Agree with your result.

Do you know the source of the case? Worth double-checking with them where the discrepancies come from (I don´t think that someone who publishes a case makes a silly mistake like this, there must be a piece of info that got lost in the way)

Cheers,

Clara

Same as the others here. Note that ~5% of cases in my experience have some kind of math error...the creators are human after all!
