20 % discount means if price is $. 100 then $. 20 is concession on it and you have to pay $. 100 – 20 = 80
when price is $ 100 you pay $ 80
so when price is $11 you have to pay 11 × 80/100 = 11 × 0.8 = $ 8.8
Sales tax @ 8.5 % means for $ 100 you have to pay $ 8.5 as tax then for $ 11 you have to pay 11 × 8.5/100 = 11 × 0.085 = 0.935

I hope you can solve Q 2 and Q 3 on same guide lines.

If something is $11.00 and it has a discount of 20%, then you can buy it for 100-20 = 80% of $11.00 = .8*$11.00 =$8.80.

Now if there is a sales tax of 8.5% on $11.00 it would be 0.085*11 = $.935 = 94 cents. The total cost with tax would be 11+.94= $11.94.

If the sales tax is applied to the discounted price 0f $8.80, then total would be $8.80 * 1.085 = $9.55.

That shouls show you how to do the rest of the problems because they are all the same. They could have been worded more clearly, though.

These are all very similar. You get a 20% discount, so you have to pay 80%.
Sale Price = Cost x 0.80
Now, you need to pay the sales tax.

Take the sale price (Cost x 0.80) and multiply by 8.5% (0.085).

Tax = (Cost x 0.80) x 0.085.

Now, add the sale price and the tax.

In another form,
Total = (Cost x 0.80) x (1.085)

If you are finding the discount or tax, multiply the regular price by the percentage. 11 x 0.20 = $2.20. 11 x 0.085 = $0.94. The final cost is figured out by adding tax or subtracting discounts.

You can do the other ones.

Homework is to train your mind and improve your ability to face a similar problem at the examinations. Sorry. Do your own homework.
