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 reason the answer is 4+1 is because you have to subtract x from 4x causing it to be just 4 and then y I have to subtract 2 from 3 leaving one then you would have to add 4+1 which equals 5
