Two phone bills one is 3000 less than double the anual bill of the other the total spent by these two services is 91,500, so what is the anual bill for each service?
If you call one n (as you did), the other is 2n-3000. The sum of the two is 91500. Thus
2n+n-3000=91500. Combine the terms with n to get 3n, Add 3000 to both sides (members) of the equation. Finally
3n=91500+3000=94500 . Divide both members by 3 to get
n=94500/3=31500
The other is 2n-3000=2(31500)-3000=60000.
The Batch button allows you to count bills in batches from 1 - 999. For example, if you want to sort into piles of 100 bills, the machine will count 100 bills, then stops. Once you remove those 100 bills, it will continue to count the next batch of 100 bills, then stops again. The machine is preset to common counting mode, To count bills in batches, press BATCH. Batching is preset to 100 bills. To change batch amount, press C to clear, and use the keypad to enter a batch number between 1 and 999. Press SET to save the setting.
