10. Alex buys a perpetuity-immediate with annual (end-of-year) payments. At an effective (11) annual interest rate of 9.2%, the perpetuity has a present value of $167.50. Each of the first 5 payments is equal to $10. Starting from the 6th payment, the payments start to increase, the current year payment is g% larger than the preceding year payment, where 0 < g < 9.2% (thus, the 6th payment is $10(1 + g)). Determine the value of g.
