Your fixed Cost = $5,800,000
Second, you need to determine you Weighted average Contribution Margin and since the breakeven you are looking at is in dollars and not units so:
CM ratio for product 1 = ($12Mio - $4.8Mio)/$12Mio = 0.6
CM ratio for product 2 = ($3Mio - $1.5)/ $3Mio = 0.5
W1 = $12Mio /$15Mio = 80%
W2 = $3Mio/$15Mio = 20%
WACM = (0.8*0.6) + (0.2*0.5) = 0.58
Breakeven in Sales = FC/WACM = $5,800,000/0.58 = $10,000,000
