With the answer choices provided, I would say it is safe to approximate in this manner... 41,000 x 5 + 18,000 x 2 = 241,000 (approx to 240,000) 52 weeks in a year (approx to 50) Now, since 50 is much like .50 we have 12,000,000 Knowing that we lessened both values in our approximation, 12.5 million is apparent. Hope this helps!

I guess 10 mil is the corest answer:
(2/7)*365*18,000+(5/7)*365*41,000=10,6 mil

One year = 52 weeks 1K = 10^3 1M = 10^6 1 week sale = weekend sale + weekday sale = (41K * 5) + (18K * 2) = 205K + 36K = 241K One year sale = 241K *52 = (241*52)K 241 * 52 = 12.5K (approx) One year sale = 12.5K * K = 12.5 M Madelaine88 wrote: Last year, a certain public transportation system solad an average (arithmetic mean) of 41 000 tickets per day on weekdays (Monday through Friday) and an average of 18 000 tickets per day on Saturday and Sunday.

average = sum/# of terms
weekdays
41000 = x/5 days
205,000 = x (total tickets sold per week)
weekend
18000 = x/2 days
36000 = x (total tickets sold per week)
so...205k+36k * 52 weeks = 12.5 mil

For whole week: 41,000 * 5 + 18,000 * 2 1000 = K Ballpark now to simplify calculations: 40K*5 + 18K*2 =200K + 36K= 236K Number of weeks in year 52, ballpark and let's calculate with 50 236K * 50 = 11,800,K ~ 12 M. which is closest to 12.5 M answer D.

so...205k+36k * 52 weeks = 12.5 mil Why are you counting 52 weeks ?  there are 4 weeks in month and 12 month in a year hence 4*12 = 48
