Mr. Oliver orders his groceries online and has them delivered to his house. His bill is $175. He has a coupon for 10% off and pl
weeeeeb [17]

The total price including the discount and tip is $ 189

<em><u>Solution:</u></em>

Given that, Mr. Oliver orders his groceries online and has them delivered to his house

From given,

Bill amount = $ 175

Discount = 10 % off

Tip = 20 %

To find: total price including the discount and the tip

<em><u>Let us first find the discount rate</u></em>

Discount rate is 10 % off which means 10 % of bill amount $ 175

Discount\ Rate = 10 \% \times 175\\\\Discount\ Rate = \frac{10}{100} \times 175\\\\Discount\ Rate = 17.5

Thus discount price is $ 17.5

Bill amount after discount = Original amount - discount price

Bill amount after discount = 175 - 17.5

Bill amount after discount = $ 157.5

He plans to give the delivery driver a 20% tip

So, he gives 20 % of 157.5 as tip

Tip amount = 20 % of 157.5

Tip\ Amount = 20 \% \times 157.5\\\\Tip\ Amount = \frac{20}{100} \times 157.5\\\\Tip\ Amount = 31.5

<em><u>Thus total amount paid is:</u></em>

Total amount = Bill amount after discount + Tip amount

Total amount = $ 157.5 + $ 31.5

Total amount = $ 189

Thus total price including the discount and tip is $ 189
