Answer:
1. $ 8.76
2.$ 936.6
3.$ 18.70
4.$ 22.44
Explanation:
Estimates:
Machine hours  154,000
Fixed manufacturing overheads $ 656,000
Variable manufacturing overheads per machine hours $ 4.5
i)	Overhead rate = total overheads/machine hours
=$ (154,000*4.5 +656,000)/154,000
=$ 8.76
ii)	Direct materials $ 390
Direct labour      $ 240
Machine hours used= 35
Total overheads= machine hours*overhead rate=35*8.76=$ 306.6
Total manufacturing costs =direct costs + overheads
=$(390+240+306.60)=$ 936.6
iii)	50 units produced
Unit product cost= total costs/ units produced
=936.6/50
=$ 18.70
iv)	If 120% markup is used what applied on total manufacturing the selling price per unit
Cost per unit =$ 18.7
Markup= gross profit/costs
120%=GP/18.7*100
120*18.7/100
=$ 22.44
