If he earns 4.3% per year, compounded annually, the equation that describes Justin's investment is 1200 = 1000(1.043)", where n is the number of years for which the money is invested. Solve the equation for n to determine how long it will take before he can buy the laptop. Round your answer to one decimal place. Estimate n n Analysis Saving
