Question

The city treasury began with $1,100,000 at the beginning of the year. Each day since tax revenues have come in at a rate of 12,500 per day. Expenditures each day average 15,000 per day. The treasury now has less than1,000,000. How many days d has it been since the beginning of the year?

Answer 1

Net daily change is revenue - expenditures, 12500 - 15000 = -2500.

The overall change in the treasury's funds is 1.1Mil - 1Mil = 100K. To find out how many days, we divide the overall change by the net daily change in revenue: 100K / 2500 = 40 days.
