Emily has a coupon for 20% off your purchase at the store she finds a backpack that she likes of just Don't Rock the original price is 60 but everything on the Rock comes with the 30% off discount Emily says what is the price

Emily's price is 33.6

Step-by-step explanation:

The original price of the backpack(just Don't Rock)that she likes of is 60 but everything on the Rock comes with the 30% off discount. It means that the amount taken off is

30/100 × 60 = 18

The price for which it was available is

60 - 18 = 42

Emily has a coupon for 20% off your purchase at the store. It means that the amount that would be taken off the backpack that she wants to buy is

20/100 × 42 = 8.4

The final price that she would pay is

42 - 8.4 = 33.6

answer: 33 ( approx)

step-by-step explanation:

since, in the linear regression formula, the slope is the a in the equation y = b + ax ( by comparing it with the general equation of line y = mx + c )

where,

here given table is,

price ($), x   :           18         23       25       29       30       33

pairs sold, y :         16         13         10       8         6       2

so, ,   ,   ,

and   ,

thus, slop of the given line is,

⇒  

⇒   ≈ 33
