Dylan's mother gets a restaurant bill for $25. She has a coupon for 15% off. After the discount is applied, she adds 20% tip for the server. What is the total that Dylan's mom will pay at the restaurant?

Given:

Amount of bill = $25

Coupon = 15% off

Tip = 20% after discount is applied.

To find:

The total that Dylan's mom will pay at the restaurant.

Solution:

We have,

Amount of bill = $25

Discount = 15%

Amount after discount = 25 - 15% of 25

So, amount after discount is $21.25.

Tip = 20%

Total Amount = Amount after discount + Tip

Therefore, Dylan's mom will pay total $25.5 at the restaurant.

answer: the price of one pound cabbage = $ 0.8

the point (10,8) represents that the cost of 10 pounds cabbage is $ 8

step-by-step explanation:

since, here is a proportional relation between the number of pounds of cabbage (x) and the price in dollars (y).

therefore, we can write,

⇒ y = k x

where k is the constant of proportionality.

now, point (5,4) is in the line.

thus, it will satisfies the above equation of line.

⇒ 4 = 5 k

⇒ k = 0.8

thus, the equation of the line is,

y = 0.8 x

a) for x = 1,

y = 0.8

therefore, the cost of one pound of cabbage is 0.8 dollars.

b) in the below graph (10,8) represents that the cost of 10 pounds of cabbage is 8 dollars.
