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 plans to give the delivery driver a 20% tip. what is the total price, t, of mr. olivers order, including the discount and the tip? t = $
Answer
# Explanation:
## Step1: Calculate the price after discount
The original bill is $175. The discount is 10%, so the price after discount is $175\times(1 - 0.1)=175\times0.9 = 157.5$.
## Step2: Calculate the total price with tip
The tip is 20% of the price after - discount. So the total price $t$ is $157.5\times(1 + 0.2)=157.5\times1.2=189$.
# Answer:
$189$
