Hello,
There are a few ways to solve this. Here's one way.
Find how many were sold in each category:
60% ----480 sold
20% ----160 sold
other 20%---160 sold
Now find the price:
50% ----$4.48 (rounded off)
30% ----$2.69 (rounded off)
Now multiply each category:
$4.48*480 + $2.69*160 + $8.95*160 = $4,012.80
Make sense?
