• Priya orders takeout from a local restaurant. Her order is $24 and she uses a coupon for
25% off. She wants to know the total price, after tipping the driver 15%.
• Complete the equation to show the relationship between the sale price, s.
and the regular price.
S= ? • ?

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 =

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 =

We are given that s denotes the sale price

So, s = 0.75r

b. 6

step-by-step explanation:

we are given the table representing an exponential function.

we can see from the table that, as x is increasing, the value of y is increasing in the power of 6.

i.e. the following relation is obtained,

x = 1, y = 6

x = 2, y = 36 =

x = 3, y = 216 =

x = 4, y = 1296 =

x = 5, y = 7776 =

so, the geometric series obtained is .

thus, the common ratio is given by = = 6.

hence, the common ratio is 6.
