You calculate the weighted average. Example:

Item 1: $100 with 10% = $10

Item 2: $500 with 7% = $35

Total = $600, total discount = $45

$45 / $600 = 7.5% discount

You obviously didn’t spend much time in math classes. Add 10% to 7% and divide by 2. That’s your average.

add together divide 100 x17 gives exact amount %

if you just want to calculate the average discount amount.

( 10% + 7% ) / 2 = which is 8.5 %

but if item 1 and item 2 have different prices, then different story.

so plug this in to your calculator.

( ( ( item 1 price ) X 10% + ( item 2 price ) X 7 %) ) / ( ( item 1 price ) + ( item 2 price ) ) ) X 100

after you times the last equation by 100, you get a percentage of discount
