Amy went to the store to buy a new pair of
designer pants. They
were on sale for 30%
off the original price. If
they originally cost
$55.00, how much
would Amy be saving
by buying them on
DED
sale?

Step-by-step explanation:

because u are use decimal and half value

x+y=90

x=30-y=x

step-by-step explanation:

if you understand you will get the answer

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.
