Answer:
The total cost is $95.32.
Step-by-step explanation:
Given:
Total came to $76.75. There is an 8% sales tax and 15% tip.
Now, to find the total cost.
<em>8% sales tax is there so we calculate the amount after adding sales tax:</em>
$76.75 + 8% of $76.75
![76.75+\frac{8}{100}\times 76.75](https://tex.z-dn.net/?f=76.75%2B%5Cfrac%7B8%7D%7B100%7D%5Ctimes%2076.75)
![76.75+0.08\times 76.75](https://tex.z-dn.net/?f=76.75%2B0.08%5Ctimes%2076.75)
![76.75+6.14](https://tex.z-dn.net/?f=76.75%2B6.14)
![82.89](https://tex.z-dn.net/?f=82.89)
The cost after sales tax is $82.89.
Now, <em>the cost after 15% tip:</em>
$82.89 + 15% of $82.89
![82.89+\frac{15}{100}\times 82.89](https://tex.z-dn.net/?f=82.89%2B%5Cfrac%7B15%7D%7B100%7D%5Ctimes%2082.89)
![82.89+0.15\times 82.89](https://tex.z-dn.net/?f=82.89%2B0.15%5Ctimes%2082.89)
![82.89+12.43](https://tex.z-dn.net/?f=82.89%2B12.43)
![95.32](https://tex.z-dn.net/?f=95.32)
The cost after the tip is $95.32.
Therefore, the total cost is $95.32.

Answer:
D
Step-by-step explanation:
The quadratic formula:
![\frac{-b\pm \sqrt{b^2-4ac}}{2a}](https://tex.z-dn.net/?f=%5Cfrac%7B-b%5Cpm%20%5Csqrt%7Bb%5E2-4ac%7D%7D%7B2a%7D)
where a is the coefficient of
, b being the coefficient of
and c being the constant.
Plug in the values:
![\frac{-\left(-5\right)\pm \sqrt{\left(-5\right)^2-4\cdot \:2\cdot \:5}}{2\cdot \:2}](https://tex.z-dn.net/?f=%5Cfrac%7B-%5Cleft%28-5%5Cright%29%5Cpm%20%5Csqrt%7B%5Cleft%28-5%5Cright%29%5E2-4%5Ccdot%20%5C%3A2%5Ccdot%20%5C%3A5%7D%7D%7B2%5Ccdot%20%5C%3A2%7D)
![\frac{5\pm\sqrt{-15} }{4}](https://tex.z-dn.net/?f=%5Cfrac%7B5%5Cpm%5Csqrt%7B-15%7D%20%7D%7B4%7D)
Since ![\sqrt{-15} =\sqrt{-1} \sqrt{15} =i \sqrt{15}](https://tex.z-dn.net/?f=%5Csqrt%7B-15%7D%20%3D%5Csqrt%7B-1%7D%20%5Csqrt%7B15%7D%20%3Di%20%5Csqrt%7B15%7D)
The answer is:
![\frac{5\pm i \sqrt{15} }{4}](https://tex.z-dn.net/?f=%5Cfrac%7B5%5Cpm%20i%20%5Csqrt%7B15%7D%20%7D%7B4%7D)
I just wrote it out so hope this helps :)
