The total price including the discount and the tip is ![$189](https://tex.z-dn.net/?f=%24189)
<u>Solution:</u>
Given:
Bill Amount = ![\$175](https://tex.z-dn.net/?f=%5C%24175)
Coupon = ![10\%](https://tex.z-dn.net/?f=10%5C%25)
So, Discount will be ![\frac{(175\times10)}{100} = \$17.50](https://tex.z-dn.net/?f=%5Cfrac%7B%28175%5Ctimes10%29%7D%7B100%7D%20%3D%20%5C%2417.50)
Discounted price = ![175-17.50 = \$157.50](https://tex.z-dn.net/?f=175-17.50%20%3D%20%5C%24157.50)
Mr. Oliver plans to give delivery driver a tip of ![20\%](https://tex.z-dn.net/?f=20%5C%25)
Now, Bill (After reducing discount) =
Tip = ![20\%](https://tex.z-dn.net/?f=20%5C%25)
Tip Amount = ![\frac{(157.50\times20)}{100} = \$31.50](https://tex.z-dn.net/?f=%5Cfrac%7B%28157.50%5Ctimes20%29%7D%7B100%7D%20%3D%20%5C%2431.50)
Now add that tip amount,
Total Price = ![157.50 + 31.50=\$189](https://tex.z-dn.net/?f=157.50%20%2B%2031.50%3D%5C%24189)
Steps to find the discounted price:
Step 1: Consider the rate of discount
Step 2: Find the actual discount by multiplying the discount rate by the original amount
Step 3: Subtract the actual discount from the original amount to find the discounted price.
