## Basic College Mathematics (9th Edition)

We know from Exercise #59 that a school would need to collect 100,000 box tops to earn the maximum amount. To find out the number collected per week in 38 weeks, we divide: $~~~~~~~~~~2631.5$ $38\overline{)100000.0}$ $~~~~~~~~\underline{76}$ $~~~~~~~~~240$ $~~~~~~~~~\underline{228}$ $~~~~~~~~~~~120$ $~~~~~~~~~~~\underline{114}$ $~~~~~~~~~~~~~~~60$ $~~~~~~~~~~~~~~~\underline{38}$ $~~~~~~~~~~~~~~~~~220$ $~~~~~~~~~~~~~~~~~\underline{190}$ $~~~~~~~~~~~~~~~~~~~30$ We can stop the division with the remainder of 30 because we only need to round to the nearest whole number: $2631.5\approx 2632$ box tops Thus the school needs to collect 2632 box tops per week.
