Average discount given for complete product line

[troymoto25]

I have been out of school for entirely too long to remember how to build this equation. I am trying to calculate the average discount given for our entire product line annual sales, that is sold over 4 distinct pricing levels. The data I have is as follows:
Baseline is a 0% discount, or a direct customer sale.
18.7% of annual sales is at 0% discount
5.4% of annual sales is at 25% discount
51.6% of annual sales is at 30% discount
24.3% of annual sales is at 35% discount
I am trying to calculate the average discount of all sales so that I can ensure our lowest discount is not negatively affecting net profits. I'd be excited to perform the calculations myself and learn where we're at, but I simply do not know how to create the equation to get the desired result.
Sincere thank you for any assistance any of you could offer me.

What is your specific definition of the "average discount" of "all sales"? For instance, are you using sales as a percentage of items sold, a percentage of wholesale costs, a percentage of retail sales at the sale prices, a percentage of retail sales at the original (marked) prices, or something else? Also, you say that there are "4 distinct pricing levels", but you then list five levels (from a discount of 0% to a discount of 35%). Kindly please clarify.

(Note: In "real life", of course, there would be an accounting department or some other professional, on-staff or available to be hired in, who could determine any equations and models needed by management.)

When you reply, it may be helpful to provide the full and exact text of the original homework exercise and the complete instructions, along with a clear listing of your efforts so far. Thank you!
