Answer 2

1) The total price, after tipping the driver 15% is 21.6

2) s = 0.75r

Explanation:

Price of order = $24

She uses a coupon for 25% off.

Discount =
`25\% * 24 = (25)/(100) * 24 =6`

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`

We are given that s denotes the sale price

So, s = 0.75r
