Problem $3-22($Algo$)$ MAPE

Two independent methods of forecasting based on judgment and experience have been prepared each month for the past $10$ mighths. The forecasts and actual sales are as follows:

$\backslash$table$[[$Month$,$Sales,Forecast $1,$Forecast $2],[1,835,830,760],[2,835,795,790],[3,805,805,830],[4,825,795,825],[5,775,795,800],[6,845,785,786],[7,815,770,790],[8,835,820,780],[9,805,815,800],[10,840,845,790]]$

Compute MAPE for each forecast. $($Round your intermediate calculations to $3$ decimal places and final answers to $2$ decimal places, using a percent format $($aka $1\mathrm{.}23\%.)$

MAPE for Forecast $1$: $\%$

MAPE for Forecast $2$: $\%$
