I hope this will help. I was really calculating maybe keep on trying on A peice of paper.:)
Answer:
Step-by-step explanation:
Solve the value of 
:
-Combine like terms:
-Take 
and subtract it from 
:
-Add 
on both sides:
-Divide both sides:
So, therefore, the value of is 
.
We need to find the percent, let's start but making the equation.
The price is 2.69
The tax cost is 0.13
So what percent of 2.69 is = 0.13.
Equation: X/100 x 2.69 = 0.13
Multiply each side by 100 so we can get x alone with the price: 2.69x = 13
Now to get x alone, we must divide both sides by 2.69: x = 4.8
Finally, we just round 4.8 to the nearest whole number, which is 5 (5 or above give it a shove, 4 or below let it go, we have 8 so we give it a shove). This means that the answer will be 5%.
I hope this helps! :)
