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.

Step-by-step explanation:
Step-by-step explanation:
y=mx+b m being the highest point x being the lowest
Assume that the number of apples is x and the number of oranges is y.
For the first given, we know that each apple costs $0.24 and each orange costs $0.8, therefore:
amount paid for apples = 0.24x and amount paid for oranges = 0.8y
we also know that the total amount spent is $12, therefore the first equation is as follows:
0.24x + 0.8y = 12
For the second given, we know that the total number of fruit bought is 20, therefore, the second equation is:
x + y = 20
You can easily graph these two functions and find a possible combination from the graph (the correct combination would be the intersection between the two lines).
