Suppose your business has a special checking account used just for paying the phone bill. The balance is $740.00 this month. Nex
t month the balance will be $707.60, after that it will be $675.20, and on the third month the balance will be $642.80. Write an explicit formula to represent the balance in the account as an arithmetic sequence. How many months can you pay your phone bill without depositing any more money in the account?
740-707.60=32.40 707.60-675.20=32.40 675.20-642.80=32.40 so that means every month you are paying 32.40$ bill. to get how many months you can pay phonebills without depositing any more money devide the 740/32.40=22.83 but you can not pay bill for the 0.83 month so answer will be 22 months
