Develop an exponential smoothing forecast $)=(0\mathrm{.}60$ for periods $11$ through $15.$ Assume that your forecast for period $10$ was $274.$

$\backslash$table$[[$Period$,$Demand$],[10,219],[11,390],[12,444],[13,263],[14,462]]$

Calculate the forecasts for periods $11$ through $15($enter your responses rounded to two decimal places$).$
