A suit cost $95 Barry has a discount coupon for 10% off and the city has a 4.5 percent sales tax what is the final cost of the suit

SO the suit cost $95 and it has a discount of 10%

so 95*10/100=9.5

so 10% of 95 is 9.5

subtract 9.5 from 95 and that equals 85.5

then you have to add 4.5 percent sales tax

so 85.5 + 4.5% = 89.347

So the final cost would be $89.34
