Answer:
1) The total price, after tipping the driver 15% is 21.6
2) s = 0.75r
Step-by-step explanation:
Price of order = $24
She uses a coupon for 25% off.
Discount = ![25\% \times 24 = \frac{25}{100} \times 24 =6](https://tex.z-dn.net/?f=25%5C%25%20%5Ctimes%2024%20%3D%20%5Cfrac%7B25%7D%7B100%7D%20%5Ctimes%2024%20%3D6)
So, Cost after discount = 24-6=18
She wants to know the total price, after tipping the driver 15%.
So, Tip to driver = 15% of 24 = 3.6
So, Cost including tip = 18+3.6=21.6
Thus the total price, after tipping the driver 15% is 21.6
Now we are supposed to find equation to show the relationship between the sale price, s. and the regular price.
Let the regular price be r
Discount = 25%
So, Discounted price =![r-25\%r=r-0.25r=0.75r](https://tex.z-dn.net/?f=r-25%5C%25r%3Dr-0.25r%3D0.75r)
We are given that s denotes the sale price
So, s = 0.75r
Answer:
-4x(5x-3)
Step-by-step explanation:
-20x^2 - 12x
-20x^2 = -4*5*x*x = -2*2*5*x*x
-12x = -4*3*x = -2*2*3*x
The common terms are -2*2*x = -4x. Whats left goes inside the parentheses
-4x(5x-3)
