Answer:
Amount left = Rs 45
Step-by-step explanation:
Let the initial amount be x.
Translating the word problem into an algebraic expression, we have;
![x - 15 = \frac {3}{4} * x](https://tex.z-dn.net/?f=%20x%20-%2015%20%3D%20%5Cfrac%20%7B3%7D%7B4%7D%20%2A%20x%20)
![x - 15 = \frac {3x}{4}](https://tex.z-dn.net/?f=%20x%20-%2015%20%3D%20%5Cfrac%20%7B3x%7D%7B4%7D%20)
Cross-multiplying, we have;
![4(x - 15) = 3x](https://tex.z-dn.net/?f=%204%28x%20-%2015%29%20%3D%203x%20)
![4x - 60 = 3x](https://tex.z-dn.net/?f=%204x%20-%2060%20%3D%203x%20)
Rearranging the equation (collecting like terms), we have;
![4x - 3x = 60](https://tex.z-dn.net/?f=%204x%20-%203x%20%3D%2060%20)
x = Rs 60
Next, we find the amount left;
Amount left = 60 - 15
Amount left = Rs 45
To find the tip of the bill. You will need to find how much of $86.40 is 20%. In this question, they're asking how much is the tip, not how much will the final price be.
When you multiply a percentage you move the decimal point 2 times to the left: 20. → .20
You would multiply $86.40 by .20
When you solve it 86.40 × .20 = 17.28
$17.28 is 20% of $86.40
$17.28 will be the amount he got for his tip.
