Answer and Explanation:
The computation is shown below:
1) Number of unit sold in 2016 is 
 As we know that 
Total contribution margin is 
= Fixed cost + Net income 
= $153,200 + $574,100 
= $727,300 
 And, the Contribution margin per unit is 
= $153 - $93 
= 60 per unit 
 So, the Number of unit sold in 2016 is 
= $727,300 ÷ 60 
= 12,122 Units 
 2) Number of unit sold is 
= ($574,100 + $153,200 + $62,200) ÷ 60 
= 13,158 Units 
 3) The selling price is 
 Break even = (Fixed cost + Desired profit) ÷ Contribution margin 
 12,122 = ($574,100 + $153,200 + $622,00) ÷ (X - $93) 
 12,122X - $1,127,346 = $789,500 
 12,122X = $1,916,846 
 X(Selling price) = $1,916,846 ÷ 12122 
= $158 per unit
