Suppose you owe $700 on your credit card and you decide to make no new purchases and to make the minimum monthly payment on the account. Assuming that the interest rate on your card is 2% per month on the unpaid balance and that the minimum payment is 4% of the total (balance plus interest), your balance after t months is given by B(t) = 700(0.9792'). Find your balance each of the given times. Complete parts (a) through (e) below. (a) six months After six months, the balance is $ (Round to the nearest cent as needed.)

Q2

It is time to clean the water tank. The process requires draining a 75-gallon tank. To siphon the water out of the tank, he uses a hose that drains 6.5-gallons out of the tank in 15 minutes. How long will it take the tank to be drained of water? a. Make a table comparing the elapsed time with the amount of water left in the tank over time. NOTE: The x-axis is usually used to represent time. b. Write an equation describing the relationship between the elapsed time and the amount of water remaining in the tank. C. Draw a graph. Discuss the meaning of the x-intercept and the y-intercept in this situation. d. Why might the information from the table in part (a) and the graph in part (b) be important to know?
