Sales Tax rate: 6.75% Total price of item including tax: $14.93Original price of item: ? Let x be the original price x+0.0675x = 14.93 -- we change the percent to decimal
1.0675x = 14.93 -- simplify 1.0675x/ 1.0675 = 14.93/1.0675 --isolate x x = 14.93/1.0675 --divide x = 13.98595 Then rounded to two decimal points, the answer would be $13.99.
The answer to this question will be 45 because you minus 15 on both sides and get 45 for 60 minus 15 and then will minus 2x on both sides and the Equation will now be x=45 and you plug it in to check
