Stephanie bought nappa leather boots 20% off if the discount saved her 23 dollars how much was the original price

115

Step-by-step explanation:

The discount equals the original price times the discount rate.

We know the discount and the discount rate

Discount = original price * discount rate

23 = original price * 20%

Change to decimal form

23= original price *.20

Divide each side by .20

23/.20 = original price *.20/.20

115 = original price

option 1 is correct.

step-by-step explanation:

y varies inversely with x and constant of variation is 4

the equation will be:

y = k/x

where k =4 so,

y = 4/x

if we put values of x of option 1 in the above equation and find values of y

y = 4/-2 => y =-2

y = 4/-1 => y = -4

y = 4/1 => y = 4

y = 4/2 => y =2

so, all the values of x and y are correct.

if we put values of x given in other options and find value of y we cannot find whole table satisfying the equation.

hence option 1 is correct.

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value
