Answer:
$14,400,000
Step-by-step explanation:
For that sales mix, the total contribution margin will be ...
5($390) +9(637) +6(897) = $13,065
The selling price of that mix is ...
5($600) +9(980) +6(1380) = $20,100
Then the sales required to produce a contribution margin of $9,360,000 will be ...
20,100/13065 × $9,360,000 = $14,400,000
