Assume that you have discovered that there is a significant unfavorable standard price variance in nuts at Muesli AG$.$ You have also noticed that there is a favorable quantity $($efficiency$)$ variance for the nuts.

Why should these standard cost variances for nuts be of concern to management? What might have caused these variances?

check all that apply:

The production line may have been wasting nuts, so the Production manager will need to provide more training to the workers.

The finished muesli may not have contained enough nuts to meet MMA requirements.

The purchasing manager may have purchased too many nuts which could spoil.

There may have been a price increase in nuts which will affect profitability.
