multiply 6 by $16.50 to get the total amount = $99

now to get the percentage discount : 99-90 (which is the difference) / 99 (original price of what it should have been )

and then multiply by 100 to get the percentage discount

apologiabiology
hmm
find cost of 6 regular ones
6 times 16.6=99

so
regular-discountedprice=discount
99-90=9

discount is 9
wait, but out of what
that is 6 jobs so
9/6=1.5 discount per job
to find the percent discount
do
discount/original times 100
1.5/16.5 times 100
0.09090909 tims 100
9.090909

so 9% discount
