You have no information allowing for the original price of the computer if no discounts nor coupons. Call the original sales price, p.

p-%280.20%29p
and THEN the coupon based on the sales reduced price.

%28p-%280.20%29p%29-%280.15%29%28p-%280.20%29p%29

The tax is based on the original retail price.
highlight%28%28p-%280.20%29p%29-%280.15%29%28p-%280.20%29p%29%2B%280.06%29p%29
You want to now simplify that.
