Sum Product?

[doublediamond111]

I have two columns

# of Sales
1
0
2
3

Avg Price
$1000
-
- (no data)
$1200

I want to get the average price of all sold units. Therefore I need to exclude the '2' sale because there is no data on the price. The answer is (1/4)*1000 + (3/4)*1200, but i dont know how to get there with formulas and a lot more data

in C2 copied down:
=IF(OR(B2="-",B2="No data"),"",A2/SUMIF($B$2:$B$5,"<>No data",$A$2:$A$5)*B2)

then sum column C
