Someone please help ! The landlord of an apartment building needs to purchase enough digits to label all of the apartments from 100 through 125 on the first floor and 200 through 225 on the second floor. The digits can only be purchased in a package that contains one of each digit 0 through 9. How many packages must the landlord purchase?

Since 1 and 2 are used at least once in half of the apartments, and no other number is used this often, either 1 or 2 will be the most frequent digit used.

Since all of the numbers of the form  appear but only 6 of the numbers  appear, 2 will be used less often than 1 and we should count the number of 1s to find the number of packages needed.

100 through 125 requires 26 ones just for the hundreds place. 100 through 125 and 200 through 225 require the same number of ones for the tens and units places; that is, thirteen.

So, there are  ones used. Therefore, the landlord must purchase  52   packages.

In this exercise we have to use our statistical knowledge to calculate how many digital packages will need to be purchased to put in all apartments, so we have to:

52 packages.

Since 1 and 2 are used at least once in half of the apartments, and no other number is used this often. Since all the numbers of the form  appear but only 6 of the numbers  appear, 2 will be used less frequently than 1, and we should count the number of 1s to find the number of packages needed.

[tex]100 \ to \ 125 = 26\\200 \ to \ 225 = 26 \\26+26= 52[/tex]
