To find the price of something with sales tax, you simply multiply it by 1.(percent as a decimal). The "1" represents the original price, while the decimal afterwards represents the percent of sales tax. In this case, 3% is .03 as a decimal, so we should be multiplying 55 by 1.03.
55
<u>x1.03
</u>56.65
<u>
</u>Using the math above, we can see that the price of the shoes with the sales tax is $56.65.<u>

The equation of a parabola that opens up and has the following x intercepts (-3,0) and (4,0) is ![y=x^{2}-x-12](https://tex.z-dn.net/?f=y%3Dx%5E%7B2%7D-x-12)
<h3><u>Solution:</u></h3>
We have to find the equation of a parabola that opens up and has the following x intercepts (-3, 0) and (4, 0)
x-intercepts of the parabola are (−3, 0) and (4, 0)
So, we can form an equation:
Also x = 4
x – 4 = 0
x – 4 = 0 is another factor of quadratic equation.
The quadratic function is:
![\begin{array}{l}{y=(x+3)(x-4)} \\\\ {y=x^{2}-4 x+3 x-12} \\\\ {y=x^{2}-x-12}\end{array}](https://tex.z-dn.net/?f=%5Cbegin%7Barray%7D%7Bl%7D%7By%3D%28x%2B3%29%28x-4%29%7D%20%5C%5C%5C%5C%20%7By%3Dx%5E%7B2%7D-4%20x%2B3%20x-12%7D%20%5C%5C%5C%5C%20%7By%3Dx%5E%7B2%7D-x-12%7D%5Cend%7Barray%7D)
Hence, the equation of the parabola is ![y=x^{2}-x-12](https://tex.z-dn.net/?f=y%3Dx%5E%7B2%7D-x-12)
The correct answer is 226.8 because if 1 ounce = 28.35 then 28.35 x 8 = 226.8 Hope this helps! ;D
Answer:
umm im kinda confused but this may be the answer if you clarified.
