Answer:

2/3

Step-by-step explanation:

you can set it up as x/y because it varies directly

so when y=6 x=72

72/6 = 12

so x will always be 12 times greater than y

x=12y

so if x=8

8=12y

y=8/12

y=2/3

Kazeer [188]
If you are looking for the sales tax then you take 89.75 times .075 this will give you 6.73 now you just add 6.73 to 89.75 and you get..

sales tax = $96.48

but if you are looking for the %off you are going to do 89.75 minus 6.73 and you will get....

%off= $83.02
