maksim [4K]
Begin by subtracting 35% from 100%, giving 65% which is equivalent to 0.65
Then multiply
147 * 0.67 =  98.49
Now for a sales tax you would want to multiply by 108.5% (or 1.085) as you are paying the previous price and them some
98.49 * 1.085 = <span>106.86165
You can round to the second decimal place since you can't have a monetary value less than a penny
your answer would be $106.86
