The total price of Mr. Oliver's order is $189 including discount and tip.
Step-by-step explanation:
Given,
Bill of groceries = $175
Coupon 10% off
Amount of discount = ![\frac{10}{100}*175=0.1*175](https://tex.z-dn.net/?f=%5Cfrac%7B10%7D%7B100%7D%2A175%3D0.1%2A175)
Amount of discount = $17.50
Bill after discount = 175 - 17.50 = $157.50
Tip = 20% of bill after discount
Amount of tip = ![\frac{20}{100}*157.50=0.2*157.50](https://tex.z-dn.net/?f=%5Cfrac%7B20%7D%7B100%7D%2A157.50%3D0.2%2A157.50)
Amount of tip = $31.50
Bill after tip = 157.50+31.50 = $189
The total price of Mr. Oliver's order is $189 including discount and tip.
