Let f(t) be the balance in a savings account at the end of t years, and suppose that y = f(t) satisfies the differential equation: y = 0.07y - 10,000 1. Determine the rate at which the balance is increasing or decreasing, if after 1 year the balance is $100000. The account balance is increasing or decreasing at a rate of 2. Determine the rate at which the balance is increasing or decreasing, if after 1 year the balance is $150000. ● dollars per year. The account balance is increasing or decreasing at a rate of dollars per year.
