Answer:
Knit units = 1,600
Hard units = 400
Explanation:
The calculation of sold of knit hats and hard hats is shown below:
For computing the  sold of knit hats and hard hats first we need to find out the total of  Knit Hats  and Hard Hats and secondly we need to find out the Break even sales in units
                Knit Hats     Hard Hats     Total
Sales a            $15.00        $25.00
Less: Variable
Expenses b         $5.00       $10.00
Contribution Margin  $10.00      15.00
c = a - b
Weight d            0.80        0.20
Weighted Contribution 8.00 Â Â Â Â Â Â Â 11.00
e = c × d
Now,
Break even sales in units  = Fixed cost ÷ Contribution margin per unit
=$22,000 ÷ 11
= 2,000 units
So,
Knit Hats to be sold = Break even sales in units × Knit percentage
=2000 × 80%
= 1,600 units
Hard Hats to be sold = Break even sales in units × Hard hats percentage
= 2,000 × 20%
= 400 units
